Hi! I have a few suggestions for ground beef.
Tacos -- I use 1/2 lb of hamburger meat, 1 pkg taco seasoning, 1 can pinto beans, 1 can corn, 1/2 bell pepper (chopped) and 1/2 onion (chopped). Brown the meat, onion and bell peppers together. Stir in taco seasoning as directed on package. Add corn and beans. We fill up our tortillas with this mix and add tomatoes, lettuce, cheese and salsa. Adding the vegetables and beans to the mix still fills us up while cutting down on our meat costs.
Another thing I make -- same meat mixture as above (you could double the recipe when you make it, and use half for this recipe), stir in 1 C salsa and 1 C shredded cheese. Pour into a baking dish. Mix up a package of corn bread and pour over the top. Bake (350 F) until knife inserted in center comes out clean.
I make sloppy joes with 1/2 lb hamburger meat, 1/2 bell pepper (chopped), 1/2 onion (chopped), 1 zucchini (diced), and 1 jar salsa. Brown the meat. Add the vegetables and salsa. Simmer until veggies are tender. Serve on hamburger buns with cheese. We eat corn on the cob and baked beans on the side.
Bisquick has a recipe for Impossibly Easy Cheeseburger pie that's all right, too. Also you could double that meat mixture, and use half of it to make BBQ beef cups (basically pressing biscuit dough into a muffin pan and filling with BBQ meat mixture). I can get those recipes to you if you're interested.
I have some chicken recipes that I'll have to add later, as I have to leave soon to get my littlie to the doctor. Hope these helped some! Happy cooking!!
