Also, for the amount of people I had over, I could not afford to use rib-eye steaks, so I used meat that was sliced for Carne Asada, then I just had to slice thin as directed in the recipe.
IN a small saucepan, bring 1-1/2 cups balsamic vinegar to a boil, then simmer gently over low heat 40 min. until reduced to 1/3 cup.
CUT meat across the grain into ¼”-thick slices, then julienne to 1"-long pieces. In a large bowl, combine dry spices. Add steak pieces; toss to evenly coat. Set aside.
IN a large nonstick skillet, heat 2 Tbsp. of the olive oil over medium-high heat. Add the onions, bell peppers and Anaheim chile and sauté 4-5 min., stirring occasionally. Add garlic and cook 1-2 min. Remove to a plate. Heat remaining oil in same skillet. Add steak and cook 2 min. until done, stirring frequently. Add the 1-1/2 Tbsp. balsamic vinegar and the Worcestershire sauce, stir to combine. Add the vegetables and cook until heated through. Drain excess liquid.
PREHEAT oven to 350°F. Cut each cheese slice into 6 pieces. Place 1 piece on each of 48 crackers, then top with approximately 1 Tbsp. of the steak mixture. Place on a foil-lined baking sheet. Bake 5 min., or until cheese melts. Place on serving plate and drizzle with the balsamic reduction. Top each with a second cracker.
