Steak Tacos with Cucumber-Avocado Salsa

This recipe is from Ellie Kriegers cookbook, "The Food You Crave". Super easy to make and so full of flavor! I love this one!
Steak Tacos
1 Tblsp chili powder
2 cloves garlic, minced (about 2 tsp)
1/4 tsp ground cinnamon
1/4 tsp salt
pinch of cayenne pepper
1 1/4 lbs top sirloin steaks
twelve corn tortillas
3 cups shredded red cabbage
1/2 cup chopped fresh cilantro
1 lime, cut into wedges for garnish
cucumber-avocado salsa (recipe to follow)

Coat a large nonstick skillet with cooking spray and preheat over medium-high heat. In small bowl, combine chioli powder, garlic, cinnamon, salt and cayenne. Rub the spice mixture into both sides of the steaks. (I like to rub the meat, cover and refrigerate for an hour to let the flavors soak in.)
Grill steaks for 5 minutes per side, turning once, for medium rare. Remove from grill and let meat sit for 5 minutes. Carve into thin slices.
Warm tortillas on grill for about 30 seconds. Place carved steaks on warm tortillas with cilantro, freshly squeezed lime juice and salsa.

Cucumber-Avocado Salsa
1 medium english cucumber, seeded and diced (about 2 cups)
2 medium avocados, peeled, pitted and diced
1/2 red onion, diced finely
juice of 2 limes
salt and pepper to taste
1/4 cup chopped fresh cilantro
3 jalapeno peppers, seeded and finely chopped

Combine all ingredients in a bowl and toss gently. Serve within an hour of preparing.
