When we lived in Texas, our favorite restaurant was Lupe Tortilla's. It's a fun family-friendly restaurant with good margaritas and great Tex-Mex food and the most amazing fajitas! Here is a copycat recipe you'll love.
Goya Adobo seasoning
Combine the ingredients to make the marinade. Cut the steak into 5-6 inch pieces and cover with marinade. Refrigerate.
Grill the steak pieces on a cast iron skillet and cook until medium-rare, about 10 minutes on each side.
Remove meat, slice against the grain into strips, and (optionally) return to pan to finish cooking.
Serve on warm flour tortillas with Mexican rice, salsa, cheese, sour cream, lettuce, diced tomatoes, etc.
