In one sentence, describe what the following article is about: Push the onion and pepper mixture to the side of the pot to make room, and add 1 pound (454 g) of ground beef. Use a wooden spoon to break the beef into small pieces and cook it on medium-high heat until it is no longer pink, which should take approximately 4 to 7 minutes. If you prefer a leaner cut of meat, you can replace the ground beef with ground turkey. Once the ground beef is browned, pour the tomatoes that you pureed in the blender into the pot with the beef mixture and stir to combine. Keep the pot on medium heat and bring it to a gentle simmer. As the beef and tomato mixture simmers, use a colander in the sink to drain the macaroni of the water that it's soaked in. Next, add it to the pot with the beef and tomato mixture, but don't stir or mix the noodles into the rest of the ingredients yet. Shake the pasta well while it's in the colander to ensure that it's as dry as possible. Before folding the pasta into the beef and tomato mixture, add 2 tablespoons (30 ml) of Worcestershire sauce and 1 cup (237 ml) of low-sodium chicken stock to the pot. Use a spatula to fold the liquids and the pasta into the beef and tomato mixture until all of the ingredients are well combined. Once the ingredients are all well mixed, cover the pot with a lid and cook on medium-high heat to bring the mixture to a hard simmer. Allow it to cook until the macaroni is nearly cooked through, which should take approximately 5 minutes. If you don't have a lid for your pot, you can press a sheet of foil over it or lay a cookie sheet across the top. To know how long the pasta should cook, consult the package's instructions. You should cook it for approximately half the recommended cooking time. You can also finish off the dish in the oven. Make the sauce as directed above, but add the Worcestershire sauce to it directly and leave out the chicken stock. Cook the macaroni halfway, and mix with the sauce and half of the mozzarella in a casserole dish. Top with the rest of the mozzarella and half of the Parmesan. Bake at 375 degrees Fahrenheit (190 degrees Celsius) for 30 minutes. Garnish with the remaining Parmesan and herbs.
Summary: Crumble the ground beef in the pot and brown. Mix the tomatoes into the pot and simmer. Drain the macaroni and add it to the pot. Add in the Worcestershire sauce and chicken stock and mix until well combined. Cover the pot and heat until the noodles are mostly cooked.

In one sentence, describe what the following article is about: Tires have a major effect on the way your car looks and feels. If you are interested in increasing the functionality of your vehicle, getting a higher-quality brand of tire for your vehicle can change your experience of driving it. This is an important trick whether you're a car modding or a "casual" car owner. Keep your area's weather in mind when you pick out tires. Some tires are specially designed to function in rain or snow. Generally speaking, the bigger your wheels are, the less responsive they'll be when you're driving. Try to strike a balance between form and function with your tires. Newer vehicles are regulated by an internal computer processor, called an ECU, or "Engine Control Unit". These computers determine how much fuel is injected into the engine at different RPMs. If you want to get an added boost (and fuel economy) from your car, you can buy an input panel for your ECU and have it installed in your car. Although it's only recommended you change an ECU's default settings if you know what you're doing, you can squeeze some extra power out of your car just by improving the efficiency of parts you already have. By cutting out fuel at precise times, you can make your car "backfire", shooting a burst of flame out the exhaust when you rev it. This is not recommended for street vehicles however, and should only be approached if you know what you're doing. Your car's exhaust has a solid effect on your car's power, as well as the amount of noise it makes. Having you exhaust and muffler replaced with something more sleek can help improve the vehicle's efficiency. Some car modders also enjoy playing around with the sound a car makes. Removing a muffler will make your car sound considerably louder. While this might make the car sound faster, it's also inconsiderate to other people using the road. Your suspension is typically padded with rubber bearings to improve the car's feel and handling. However, these erode with time. Replacing them with durable polyurethane may be a largely invisible improvement to your vehicle, but it can do wonders for a vehicle's handling if you've been driving it a while.
Summary:
Change your tires. Reprogram your vehicle's ECU. Upgrade your exhaust system. Replace your suspension bushings with polyurethane.
