Vegan fajitas are a go-to camping favorite of mine. They are so easy to make! I substitute Portobello mushrooms for the traditional steak or chicken, then couple that with some richly charred peppers and onions. And fajita seasoning is one of my favorites! A combination of garlic, cumin, cilantro, cayenne pepper, salt and sugar this slightly sweet, but still plenty spicy seasoning is a wonderful complement to the peppers and onions.
