Ok, so here we go:
1 orange, juiced (or 1/2 cup orange juice)
2 lemons or limes, juiced
4 Tbsp oil
2 garlic cloves, chopped
3 chipotle peppers in adobo sauce
3 Tbsp chopped cilantro
1 tsp cumin
1 tsp salt
2 1/4 lb skirt or flank steak
Mix all the marinade ingredients in a blender. Add it to the meat. Marinade for up to 24 hours. Grill it. Chop it finely and serve it on corn tortillas whichever way you love your tacos.
This is a rocking recipe and the meat comes out tasting better than any restaurant you go to! No wonder I'd much rather eat at home! HA! No, but seriously, jokes aside, this recipe will turn your flap meat into an amazing world of flavor.
