While meat and veggies are cooking, prepare the 4 bell peppers by slicing them in half lengthwise and removing seeds and ribs. Place them in a 9x13 baking dish...you man have to use an additional smaller dish if you peppers are large
If desired, sprinkle a little bit of grated cheddar cheese over your peppers and then pop them back in the oven for a few minutes, until cheese is melted
Plate and devour!
