To make this 20-minute vegan curry even faster, buy precut veggies from the salad bar at the grocery store. To make it a full, satisfying dinner, serve over cooked brown rice. When shopping for simmer sauce, look for one with 400 mg of sodium or less and check the ingredient list for cream or fish sauce if you want to keep this vegan. If you like a spicy kick, add a few dashes of your favorite hot sauce at the end.
