Bengali Chicken Curry with Potatoes

Heat the olive oil in a large skillet over medium-high heat. Cook and stir the onions in the hot oil until translucent, about 5 minutes. Add the ginger-garlic paste and continue cooking another 5 minutes. Reduce heat to medium; stir the tomatoes into the mixture and cook until the tomatoes are pulpy, 5 to 10 minutes. Season with the cayenne pepper, curry powder, garam masala, turmeric, and cumin; cook and stir another 5 minutes.
