In a blender, add all the green sauce ingredients and blend. You may need to add lettuce in batches depending on your blender size. Pour into a bowl and set in the fridge.
Preheat coals for your grill in a chimney. While the coals are heating up. Cut up peppers and onions into large chunks and begin cooking bacon. Drain bacon from grease and set aside.
Place carne asada directly over coals and vegetables awa from coals. Grill for about 10 minutes until internal temperature is between 150-160F. Finish vegetables off over direct heat. Optionally, char jalapenos over direct heat.
Chop up carne asada, bacon, and vegetables into bite size pieces. Slice jalapenos vertically. Assemble into tacos and top a jalapeno slice and your favorite salsa!
If you are not familiar with carne asada I recommend visiting my link for my carne asada recipe. It is marinated flap meat (or sometimes flank steak depending on your location). It can be marinated overnight in Mexican seasonings. Or to keep it simple season with salt, pepper, and grill up!
