You should be able to find everything you need for this simple curry at a well-stocked grocery store. Feel free to change up the vegetables, as long as you slice them so they’re all pretty small and about the same size. You could try broccoli, cauliflower, mushrooms, diced butternut or sweet potato (which will probably require a longer cooking time), sliced zucchini and/or yellow squash. Let me know how it turns out for you!
