1 12-ounce bottle pilsner beer
1/4 cup fresh-squeezed lime juice
1 medium onion, finely chopped
3 cloves garlic, minced
1 jalapeño pepper, seeded and finely chopped
1/4 cup fresh cilantro, chopped
Just sprinkle the steak with salt (not too much!) and fresh pepper, very lightly coat with heart-healthy olive oil, and place in a large plastic bag. Pour in marinade, making sure steak is entirely submerged. Marinate for at least two and up to six hours — then throw on the grill, cook to at least 145 degrees Fahrenheit for safety, and enjoy!
I just threw all the ingredients in a food processor and wazzed them all up together. Took about 5 minutes.
Also, I decided to salt and pepper the steaks after marinating them. I know the marinade won’t penetrate as well without the salt, so I am upping the marinade time to 24 hours. I usually like to marinade for at least 24 hours anyway, because I think all the stuff about 8 hours being all it takes is horseshit. No, I don’t care what Alton Brown says. Or America’s Test Kitchen.
