Good Carne Asada recipe

This has become my easy, go-to-in-a-pinch recipe.
Ingredients:
2 lbs flank or skirt stake. I get mine from my grocer who has pre-sliced it into 1/8" strips. Makes it really easy and quick.
Marinade:
4 garlic cloves, minced
3 or 4 roasted peppers, your call. I get mine from a pepper roaster at our local farmers market - usually a medium anaheim. I did not know this, but they claim they grow about 15 different varieties of anaheims, from very mild to medium hot.
1 teaspoon freshly ground cumin seed: real important to not use pre ground - the fresh ground does make a difference. I use an old pepper grinder that I keep filled with cumin seeds.
Handful of cilantro, leaves and stems, finely chopped (great flavor in the stems for marinating)
Kosher salt and ground pepper
2 limes, juiced
2 tbsp white vinegar
1/2 teasp sugar
1/2 cup olive oil
Method:
Lay the steak in a non-reactive dish; combine the marinade ingredients and pour over the meat, tossing to coat all sides of all pieces of meat. Cover in plastic wrap and refrigerate for 3-4 hours.
Heat the grill to med-high. Cut an onion in half and use a long fork or prong to rub the onion over the grate. Season the meat with salt and pepper, toss well and remove from the marinade and place on the grill.
Because they are pre-sliced, they will grill very fast, less than 2 minutes per side. I do this in batches and move the completed pieces to the grill's warming tray. Once they are all done, I put it in a pile on a chopping block and let sit for a few minutes, then have at it with a meat cleaver.
If your date is still there in the morning, save some for breakfast burritos with a couple of mimosas. Unbelievably tasty and apparently, an aphrodisiac also. Who knew??
