In a large skillet, heat the olive oil over medium heat. Add the finely chopped onion and sauté until soft and translucent, about 5 minutes.
Stir in the minced garlic and grated ginger, cooking for an additional 1-2 minutes until fragrant.
Add the Tikka Masala spice blend, ground cumin, and turmeric powder to the skillet. Stir well to coat the onions in the spices and cook for 1-2 minutes.
Pour in the canned diced tomatoes (with juices) and stir to combine. Simmer for about 5 minutes, allowing the flavors to meld.
Add the drained chickpeas and stir to incorporate. Pour in the coconut milk and bring to a gentle simmer. Cook for 10-15 minutes until the sauce thickens slightly.
Add lemon juice and season with salt and pepper to taste. Stir well and remove from heat.
Serve the chickpea tikka masala hot, garnished with fresh cilantro alongside cooked basmati rice or warm naan.
Notes
