grill.
Grill stuffed peppers? That's like grilling water.
I'm going to suggest that you clean the peppers and cook them in boiling water for three minutes. If you are using ground beef, cook that first and mix it with the rice and other ingredients. Then you can bake without liquid and the peppers will be tender and the filling well cooked.
Just add some water. The water and steam, assuming you'll be using a lid, will help them cook. You could also use chicken, beef or vegetable broth.
Sorry, but after seeing you post this simple question in a thread I have to ask; did you cook the rice before stuffing it into the peppers?![]()
