These Fajitas de res are so juicy, tender, and amazingly flavored! Crispy bell peppers and onions tossed with beef steak and served over a warm tortilla with guacamole and salsa.
Place the beef in a mixing bowl. Add 2 tablespoons of oil, lime juice, garlic, cumin. Generously season with salt and pepper.
Pour the beer and mix thoroughly until the beef is nicely coated with the marinade.
Cover the bowl with cling film and place in the fridge allowing the beef to marinate for at least 30 minutes.
Heat a griddle or a cast iron skillet over medium-high heat. Add a drizzle of oil and grill the peppers with a pinch of salt and pepper until they start to soften on the inside but they’re still crunchy on the outside.
Remove the peppers from the griddle and place them in a bowl. Cover with foil to prevent vegetables from drying out.
Now cook the onions the same way as the peppers and once cooked place them in the bowl with the peppers.
Add a generous drizzle of oil to the pan and add the meat. Cook stirring constantly until the meat has changed color and is cooked through (about 4 minutes).
Return the vegetables to the pan with the meat, give a quick mix, and turn off the heat.
Serve the fajitas de res hot along with your favorite sides.
