Cut poblano peppers in half, remove seeds and veins, and cut into strips.

Add 2 tablespoons of oil to a sauté pan. Add the onion and pepper strips. Sauté until the onion is tender. Remove from pan and set aside.

Heat the remaining oil in the pan. Drain the beef and add to the pan. Sauté quickly to brown the beef, add the onions - peppers back to the pan. Stir fry for 1 minute more.

Place a tortilla on a griddle. Sprinkle with some of the melted cheese, beef mixture, cilantro and top with more cheese. Cover with another tortilla. Grill until cheese melts and tortilla is browned.

Cut into wedges and serve. Repeat with remaining tortillas and beef until it is all gone.
