It's much easier on your budget to stretch out one pound of steak with all of these assorted veggies & accoutrements, rather than going with a basic steak-and-potatoes recipe that requires more meat per person.
1medium yellow onion, quartered then sliced into strips
2small bell peppers or one large one (I used red and yellow), sliced into strips
8ozsliced mushrooms

Instructions
Top steak with: 2 cloves chopped garlic, 1 tablespoon of the olive oil, lime juice, cumin, chili powder, serrano or jalapeño, and seasoned salt, then let marinate. (I just quick marinated while slicing the rest of the veggies, but you can let it go longer in the fridge for more flavor and tenderness.)
After marinating: Heat 1 tablespoon of olive oil in your 12" cast iron skillet on medium-high heat until shimmering, swirl to coat the bottom of the pan, then add the steak and cook for three minutes per side (or until cooked through medium rare). Remove steak from pan and let it rest while you cook the veggies.
Add another tablespoon olive oil to the same skillet and scrape up the browned bits on the bottom. Add onion to the pan and cook for one minute over medium-high heat. Add one clove chopped garlic and the mushrooms and cook for another two minutes, stirring occasionally. Add another tablespoon of olive oil and the bell peppers, then continue sauteing for another three minutes, stirring occasionally, until peppers are crisp-tender. Turn off the heat under your pan.
Slice steak thinly against the grain. Serve steak fajitas with accompanying veggies on tortillas with your choice of toppings. (Shredded cheese, avocado, sour cream, tomatoes, lime wedges, pico de gallo, salsa, etc.)
Notes
The meat and veggies here are naturally low carb and gluten free, so MashupDad enjoyed his steak fajitas on a low carb wrap (and you can easily serve them on corn or other gluten free tortillas, if you're gluten free). Run your oven fan and open a window if possible, and avoid breathing in the peppery fumes -- this recipe is kind of smoky, but worth it! :)
