Heat some vegetable oil, fry chili. Add curry paste, fry a bit, and then the onions, chopped. When onions are sautéd/glassy, add coarsely chopped tomatoes and reduce. Finally add spinach and melt / mix, not forgetting the garlic and other spices/herbs/chutney at this point. Now is a good time to stick the naan into the oven, and when that’s done, serve. Sprinkle diced feta on top. Serve and enjoy.
