This recipe is my husband's FAVORITE recipe. If I allowed him to, he'd make it 365 days a year. It comes from his mother, and it is really good. Just a warning for those who like their Mexican spicy -- this is not very spicy!
Fry ground beef on high. Turn off heat. Add bean and sausage mix, ½ package of cheese, can of Mexican tomatoes, and lettuce to ground beef while meat is still warm. Stir until mixed well.
Spray a 9 x 13 with non-stick cooking spray. Place flour tortilla in hand, scoop some meat mixture onto flour tortilla, and roll into burrito. Check burrito for filling size (is it too much/too little?) and adjust accordingly. Place newly formed burrito overlapping-edge-side down into pan. Line pan with burritos until meat mix is gone.
In separate bowl, mix enchilada sauce and tomato sauce. Pour mix evenly over burritos. Cover and bake at 350*F for 40 minute. Sprinkle remaining cheese over top. Bake for another 5 minutes, until cheese is melted.
