How about shepherds pie? Brown some ground beef and drain. Chop up a small onion and cook it til translucent. Mix the beef, onion and a can of drained corn (or you can use frozen) in a casserole dish. I like to grate some cheddar cheese and mix it in also. Top with mashed potatoes then a layer of mozzarella cheese. Cook 350 for about 30 minutes.
Stir fry is very simple. Marinate your meat if you want to but you don't have to. Stir fry in a little oil then remove. Add your cut up veggies and cook til tender crisp. Add the meat back in with whatever "sauce" you want to use. I usually just use chicken broth and thicken it up with a past of corn starch, water and soy sauce.
What about breakfast? It's inexpensive and always a go to meal for my house.. I mix it up and will do eggs, toast and turkey bacon..... eggs, toast and sausage links... pancakes.. I have thrown chocolate chips in the pancakes sometimes too, my kids love them.
Take chicken and cut into bite sized pieces. Put it in a bowl that you can cover and add 1 bottle of italian dressing. Set it in the fridge over night. When ready to cook it dump it all in a frying pan (With the italian dressing too) and I cut up onions and put it in with mine.. Cook until the chicken is done and then I drain the extra italian dressing off and cook a little while longer to brown the chicken.. I serve ours with long grain and wild rice.
Steak... I buy whatever steak is on sale. At my grocery store I can normally get 2 steaks for around $5.. I put butter (lots of it) in a frying pan, add my steak, season it with garlic salt, pepper and a little seasoned salt, cut up an onion and add it in.. Cover and let it cook until it's done. Our steaks are always juicy and so good..
I normally serve our steaks with fried potatoes and onions.
