Ingredients
In low-carb tortillas: Warm low-carb tortillas instead of lettuce leaves for classic handheld fajitas, at about 4 g more net carbs per person.
- Warm the tortillas in a dry skillet 20–30 seconds per side and fill each generously with the fajita mixture and toppings.
Vegan (tofu): Pressed tofu strips replace the halloumi and the sour cream is skipped; guacamole brings the creaminess.
- Press the tofu for 20 minutes and season it with the salt along with the spices — unlike halloumi, it needs it. Sear 2–3 minutes per side, until golden and crisp at the edges.
With portobello strips: Meaty strips of portobello seared with the peppers make the fajitas heartier and stretch the halloumi further.
- Sear the mushroom strips in the extra oil over high heat 4–5 minutes, until browned, before cooking the peppers, and toss them back in at the end.

Instructions
-
Mix the chili powder, cumin, smoked paprika, garlic powder and oregano. Toss the peppers and onion with 1 tablespoon oil and half the spice mix. Pat the halloumi dry and toss it with the remaining spice mix.
-
Heat a large cast-iron skillet over high heat. Add the peppers and onion and cook 6–8 minutes, tossing only occasionally, until charred at the edges but still crisp-tender. Tip onto a plate.
-
Lower the heat to medium-high and add the remaining oil. Lay the halloumi in a single layer and sear 1–2 minutes per side, until a deep golden crust forms.
-
Return the vegetables to the pan, squeeze the lime juice over and toss once.
-
Serve right away in the lettuce leaves, topped with guacamole, sour cream and cilantro, with lime wedges on the side. Homemade chunky guacamole is ideal here.
Tips for success
-
Serve halloumi hot. It is soft and squeaky straight from the pan but firms up and turns rubbery as it cools.
-
Don't salt anything — halloumi is brined and salty enough to season the whole dish.
-
Pat the halloumi dry before searing; surface moisture makes it spit in the pan and keeps it from browning.
Nice to have, not needed
- A cast-iron skillet gives the best char on the peppers — any heavy skillet works on high heat.
- Pickled jalapeños or a spoonful of pico de gallo add brightness — nice, not needed.
Storage & meal prep
- Keeps 2 days in the fridge
- Doesn’t freeze well
Reheat: Warm in a hot skillet 2–3 minutes, until the halloumi softens again, then add the cold toppings.
Prep tip: Slice the peppers and onion and mix the spice blend ahead — dinner then takes 15 minutes.
Best eaten fresh. Leftovers keep 2 days in the fridge; reheat in a hot skillet to soften the halloumi again.
