Equipment

  • Gallon sized Zip-Lock Bags Ideal for marinating chicken and steak, these zip-lock bags keep everything sealed and spill-proof for refrigeration.
  • Grilling Tongs These stainless steel grilling tongs by OXO are perfect for quick grilling.
  • Cutting Boards This 3-Pack of non-slip cutting boards are a fantastic tool for every home cook.

Ingredients
  

Marinade:

Vegetables:

For Serving:

  • Flour or Corn tortillas

Instructions
 

  • Marinate the steak by whisking together the steak marinade; water, olive oil, lime juice and taco seasoning. Place flank steak in a resealable plastic bag, or dish with tight fitting cover. Pour marinade over meat. Marinate for at least 2 hours, or for up to 24 hours.
  • Preheat your gas or charcoal grill to medium high heat.
  • Skewer mini peppers and quartered onions. Brush lightly with olive oil and top with salt and pepper to taste.
  • Place steak and vegetable skewers on hot grill. Cook steak for 6-8 minutes per side for a medium-rare doneness. Approximately 10 minutes per side for medium. Internal temperature of steak should read 130-135 degrees. Continually turn vegetables until all sides are lightly charred.
  • Remove steak from grill and let rest 10 minutes before slicing. While meat is resting, slice vegetables for serving.
  • If desired, lightly grill tortillas for a slight char, approximate 1 minute per side.
  • Serve with loaded guacamole and southwestern corn salsa.

Notes

Don't have an outdoor gas or charcoal grill? No problem: use an indoor grill pan. Sear the flank steak on each side over medium-high heat for 8-10 minutes per side. Grill vegetables same time, turning every 4-6 minutes.
If using wood skewers for the vegetables, be sure to soak in water before grilling. Metal skewers are also very useful, and don't require any pre-soaking prior to grilling.
