In a small 2 cup measuring cup, or something similar size and shape, combine all the marinade ingredients. Using an immersion blender, puree the marinade until smooth. Transfer to a re-sealable plastic bag and add the steak, seal and shake to coat. Refrigerate the beef for 2 to 4 hours to tenderize and flavor the beef.

Preheat a ridged grill pan on high heat.

Drain the marinade from the beef. Lightly oil the grill or grill pan. Season liberally with salt and freshly ground black pepper. Grill the steak over medium-high heat and cook for 4 minutes on each side and then transfer to a cutting board and let rest. Depending on the size of your grill pan you may need to cook in batches.

Once the beef is off the grill pan and resting, add the bell peppers and onions tossed with lime juice and olive oil, if using. Grill the mixture for 7 to 8 minutes until the vegetables are just barely limp.

While the peppers and onions are cooking, heat up the tortillas. Turn any free burners on a medium low flame. Place a tortilla on each flame and let it char about 30 seconds to 1 minute, flip the tortilla and repeat on the second side. Once heated and charred remove the tortilla to a clean tea towel and wrap to keep warm. Repeat until you have warmed all of your tortillas.

You can also heat your tortillas in a microwave, lightly dampen a tea towel with some water, wrap the tortillas in the damp towel and heat in the microwave for about 1 minute. Check to see if they are warm, if not repeat the heating at 1 minute intervals until they are warm and pliable.
