Lighter Beef Tacos

I found this recipe on Marthastewart.com. I was looking for a taco recipe because I didn't have a packet and I needed to know what seasonings to use. I have never bought another seasoning packet again. Mainly because they are packed with MSG. Which we all know is horrible for you. So, use this recipe from now on!

1 large onion
2 bell peppers
3 garlic cloves
2 tablespoons tomato paste
2 teaspoons chili powder
1 1/2 teaspoons ground cumin
Course ground salt and pepper
3/4 lb. ground beef

Saute onions and bell peppers and cook until crisp-tender. 3-5 minutes. Add garlic, tomato paste chili powder and cumin. Season with salt and pepper. Add beef. Cook breaking up meat with a MIX AND CHOP! Until no longer pink. About 5 minutes. Add 1/2 cup water and let simmer, mixing all the ingredients and allowing a sauce to form. Serve warm over tacos, burritos, or taco salad!
