Stuffed peppers takes some work. Rather than use some overly sweet jar of tomato sauce I always opt to make my own. Luckily we had some leftover brown rice from the chicken stir-fry the other night. I seasoned and browned one pound of ground beef along with some onions and then mixed the rice and meat together. Next I added my tomato sauce until it was a thick ragu. After microwaving the bell peppers to soften them I spooned in the rice, meat, tomato sauce mixture. The peppers cooked in a 350F oven uncovered for 40 minutes.
