Feel free to switch up the meats as you like or use what you have on hand. Italian Sausage, Ground Turkey, Ground Chicken, Ground Pork, Ground Veal, etc. are all great choices. Or use a combination of two or three. OR, if you'd like to go vegetarian skip the meaty sauce altogether! The cheese as well can be substituted. Use cottage cheese instead of ricotta, use fresh mozzarella in place of shredded. You could even add other cheeses, like cheddar or colby jack! The options are endless! Use a different pasta shape. Any long pasta noodle will work here, like Angel Hair, Linguine, Fettucini, etc. Substitute dry herbs (or Italian Seasoning) for the fresh basil and oregano. Add in a little Red Pepper Flakes for some heat! The moral of the story is, this pasta bake is so versatile you can easily make it your own.
