My kids' favorite sauce for pasta is vodka sauce, and SO easy. I grind up a package of sliced or cubed pancetta, brown it with a chopped onion for about 15 minutes, add a 28 ounce can of tomato sauce, bring to a boil and simmer for about 10 minutes, turn off heat, and add a pint of heavy cream. Then you are supposed to add a shot of vodka, but I always forget that part.
Another weekly is chicken noodle soup. I usually get a $5 costco chicken for this. Bring a big pot of chicken broth to a boil, add chopped carrots, celery, and onion, boil until soft, blend all together with hand mixer (some of mine used to pick out the veggies), add egg noodles, boil 7 minutes, adding shredded chicken at the end. I serve with bisquick bisquits, which have to be the easiest thing on earth to make.
A big favorite is make ur own chipolte. I buy whole wheat burrito sized tortillas, and make some kind of meat filling (sometimes just seasoned grilled boneless chicken breasts, which I slice). Topping include rice, sour cream, salsa, nuked onions/peppers, cheese, olives, beans... Lay a tortilla on some foil, add fillings, roll like a burrito, and then wrap with the foil. Bake in the over (400?) for 5 - 10 minutes, until hot and steamy.
