Stuffed Chiles 4 large poblano chiles, rinsed and dried 1 large can refried beans 1 small can kernel corn 1 small jar salsa 4 ounces cheese shredded cooked white rice, optional cilantro chopped, optional onion chopped, optional olives slices, optional Roast and peel peppers. Remove seeds and clean well, making one slit in the pepper from stem to end and place peppers in foil to be folded individually. Mix ingredients together in a bowl and stuff peppers. Fold foil so ingredients can't escape. Grill about 20 minutes on low heat. You can add sour cream to top it if you like.
