This stir-fry is great as a vegetarian option for dinner or can be served as a side dish for 6 people. The toasted sesame seeds add a great finishing touch to the recipe. The exact constituents of the stir-fry can be varied according to what you like and what’s available, but the trio of beans, peppers and carrots is particularly attractive. Serves 3-4 as a vegetarian main course, 6 as a side dish.
