Ready, Set, Cook! Reynolds Wrap Contest Entry. This recipe combines traditional Mexican flavors and creates a fun "stack up" meal. It uses Reynolds Wrap Aluminum Foil to steam off the skin of the poblano pepper, as well as tent the dish while baking. This can be served as a main dish casserole or a yummy appetizer if sliced into small pieces.....great football food. Six servings as a main dish casserole or 12-15 appetizer sizes. If you like things hotter, add some diced jalapenos and garnish with jalapenos as well. Enjoy!
