Here's a super easy little thing to make when you want the flavor of Mexican food.
1 lb. ground beef
chopped onion, green pepper, garlic
1 can (14.5 oz) diced tomatoes (with green chilies is good) (juice and all)
1 can red kidney beans (rinsed)
1 can black or pinto beans, if you like
1 can sliced olives (drained)
1 can corn (with juice) (optional, I don't like corn so much ...)
1 can tomato sauce
1 pkg taco seasoning
1 cup water
Brown the meat with salt, pepper (drain fat). Cook up chopped onions, green pepper, and garlic. Break out your handy dandy can opener and start dumping. Pour in the taco sauce and water and heat it all up. You can eat this as soon as everything is warmed through or throw everything in the crockpot and let it simmer happily for hours on end. Serve with shredded cheese, sour cream, and taco chips. Lots of variation possibilities, someone I know throws in a package of dry ranch dressing mix. Just use what you like and have.
