Wash and clean the zucchini and cut into small cubes. Rinse the sprouts in a colander. Take the peas out of the package.
Heat the butter in a large pan. Add zucchini and peas and sauté for 5 minutes over medium heat, stirring occasionally. Add sprouts and fry for 1 minute. Season with salt, pepper, lemon zest and soy sauce.
Beat the eggs on top and let set in 5 minutes, lightly salt and pepper. Garnish with basil leaves.
Serve with wholegrain toast.
Variation: Briefly mix the eggs, 1 tablespoon crème fraiche, salt and pepper with a fork. Pour over the steamed vegetables and let set over low heat.
