You'll save prep time by using ingredients already available as leftovers from a previous meal or by prepping ingredients for the week together. A smart way to integrate Stuffed Peppers with Cheese into your meal plan would be to plan a meal with rice early in the week and save a couple of cups of cooked rice for the stuffed peppers.  The recipe is flexible and you could use either the raw onion that is called for or sautéed onion. If you are sautéing onions for a recipe earlier in the week you can save ¼ sautéed onion to use in the filling for the stuffed peppers. (I don't recommend saving chopped raw onions since they get stronger and change texture after chopping.) Sample Menu:  Day 1 - Grilled Steak (reserve leftover steak) Day 2 - Beef and Broccoli over Rice (uses leftover steak; make extra rice) Day 3 - Hash Brown Soup (make extra sautéed onions) Day 4 - Southwestern Stuffed Peppers with Cheese (uses leftover rice and leftover sautéed onions)
