Mix the spices in a small bowl. This is your flavor orchestra, so give it a good stir until everything is friends. Set aside.
Heat olive oil in a skillet over medium heat. Add onion and garlic, cook until soft and fragrant, about 3–4 minutes. No caramelization drama—keep it simple.
If using chicken, add it now and brown on all sides. If using chickpeas, skip to the spice step to let the flavors cling on.
Sprinkle the spice mix over the meat or chickpeas. Stir to coat evenly, cooking for another 1–2 minutes to bloom the spices.
Pour in crushed tomatoes. Stir, bring to a gentle simmer, and cook until the sauce thickens slightly and coats the ingredients, about 8–10 minutes.
Taste and adjust salt and pepper. If you like a touch more brightness, a squeeze of lemon completes the dish nicely.
Garnish with chopped parsley or cilantro. Serve hot and enjoy the warmth that says, “Yes, I nailed this.”
