Slice the beef, pepper, and onion into
thin strips. In a large skillet, heat the oil over
medium-high heat. Add meat, pepper, and onion. Sauté 6 to 8 minutes, until the meat
is well browned and cooked through and the vegetables start to
soften. While the meat is cooking, heat the
tortillas in the microwave, if desired. Wrap the tortillas in a clean kitchen
towel or in plastic wrap. Lay the wrapped tortillas on a plate
and heat them in the microwave on high for 45 seconds. Place all the toppings on the table. Squeeze the lime (or lemon) juice over
the meat mixture. Season with salt and pepper, place in
a bowl, and serve immediately.
Fajitas might sound complicated, but if
you've got store-bought tortillas, store-bought salsa, ready-grated
cheese, and sour cream, if you like, you can plunk them on the table and
let everyone assemble their own. All you need to do is cook the meat
(and you can use chicken instead of beef).
Serve a green salad on the side to add a
little vegetation to your meal.
