Remove jalapeños and allow to cool. Chop jalapeños and add to the bean mixture. Layer cheese on top of dip. Close the lid to the grill and let the cheese melt and become bubbly. While the dip is heating, grill the tortillas on direct heat until they develop char marks on each side.
Using an oven mitt or thick kitchen towel, move the skillet onto a heat resistant surface and allow the dip to cool. Garnish with cilantro and diced red peppers to serve. Grill tortillas after removing the dip from the grill. Remove tortillas; allow to cool. Slice into wedges that can be dunked into the dip like a "skillet nacho."
