In a large skillet, saut onions, peppers, mushrooms, & garlic in a couple tablespoons of oil or butter.
Once veggies are softened, add ground beef and seasoning. Stir and cook until browned.
Drain some of the grease from pan, then add rice & stir
Add broth and bring pot to a rapid boil, stirring occasionally.
Let boil for about 5 minutes uncovered, stirring so rice doesn't stick or burn.
Reduce heat to medium low and cover. Cook for 10-15 minutes, without stirring.
Most of the liquid should be absorbed at this point. If not, cook 5-10 minutes more.
Add cheese, cover and cook 5 more minutes.
