Great time of year to fire up the BBQ...here is one of our home-runs! Cooks' note: ° If you aren't able to grill, onions (no need to skewer) and steak can be cooked in a lightly oiled well-seasoned ridged grill pan over moderately high heat and tortillas can be toasted over gas (hold with tongs) or directly on top of electric burners. Cut skirt steak into pieces to fit in grill pan and grill in batches without crowding. Special equipment: metal skewers or a grill basket. Please note: this is an adopted recipe and I hope to make it soonest. If you make it before I do, I would appreciate feedback, Thanks ! ZWT REGION: Mexico, TexMex.
