Season the chicken chunks with salt, pepper, curry powder, paprika, coriander, and turmeric. Toss to coat evenly. No shy spices here—give them a little pep talk.
Heat oil in a large skillet over medium-high heat. Add chicken and cook until browned and cooked through, about 5–7 minutes. Remove and set aside. You want some color, not a boring gray blob.
In the same skillet, add a touch more oil if needed. Fry onions and potatoes until they start to soften and caramelize around the edges, 6–8 minutes. Starchy goodness with a side of crispy edges—chef’s kiss.
Return chicken to the pan. Add garlic and bell pepper. Stir-fry for another 2–3 minutes until peppers are tender but still vibrant. Taste and adjust salt if necessary.
Warm flatbreads or tortillas in a dry pan or microwave for a quick minute. Spoon the spicy mixture into each flatbread, fold, and eat with gusto. Optional squeeze of lemon brightens things up.
