Chicken. All can be served with your favorite grain and vegetable side:
1. Parmesan chicken - 1 c up parmesan cheese, 1 tbsp of Italian seasoning (I used McCormick Perfect Pinch salt-free). Wet chicken breasts, coat with seasoned cheese and bake at 375 for 25 minutes or so until done.
2. Salsa chicken -

3. Classic continental chicken. Chicken medallions (you can use chicken tenders to make this easier). Brown butter. Brown chicken in butter. Add chopped or chiffonade of basil. When done, squeeze 1/4 to 1/2 lemon over the chicken. Also works great with Salmon, but you have to be gentle cooking the salmon and it cooks faster.
All are under 1/2 hour recipes.
Beef:
Shephard's pie. I make mashed potatoes on the weekend. Then just brown beef (I add Onion soup mix to the beef), put on the bottom of pie plate or baking dish, cover with frozen carrots and peas mix (I usually microwave them about 3 minutes so that I don't need to bake the final dish as long). Cover with mashed potatoes, bake until the potatoes are browned about 20-30 minutes.
Mac & Beef: Brown beef in Dutch oven with olive oil (if you use less fatty beef, you can omit if you use fattier ground beef) chopped onion and minced garlic. Add crushed tomatoes, tomato paste, basil, oregano, and al dente macaroni. Should be very thick and not too liquidy. Add grated parmesan or romano cheese. Cook stirring occasionally. Nice variation of spaghetti and meatballs, but served as a one-pot dish. I make the pasta, pour out and use the same Dutch oven for making the final product, so that the only other dish I need is the collander.
Beef stew. Night before, brown beef, with onions and garlic. Cube potatoes. Dice carrots. Can all be tossed in the same tupperware or ziploc bag. Morning, toss prepped mixture, water, canned tomatoes, and soy sauce into a crock pot. Cook on low all day. When you come home, make some egg noodles and serve.
