Simple and tasty, these stuffed peppers with ground beef, rice, and corn make an excellent everyday family dinner. The recipe is simple, but it is versatile as well. For southwestern flavored stuffed peppers, add about 1 teaspoon of chili powder to the ground beef mixture along with a dash of cayenne. Top the stuffed peppers with pepper jack cheese just before they are finished baking. For low-carb stuffed peppers, leave the rice out and increase the other ingredients or replace the rice with drained and rinsed canned black beans.
