4 Fry vegetables
While the steaks are resting, return the pan to a high heat with a drizzle of vegetable oil. Once hot, add the peppers, onion and zucchini and stir-fry for 3 min or until slightly softened (see pro tip). Add the fajita seasoning (spicy!), a splash of water and a pinch of salt. Stir for a final 1 min until the water has evaporated.
