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.
