For a portable and flavorful veggie sandwich, make a grilled vegetable wrap using your food processor. Process bell peppers, zucchini, onions, and mushrooms until finely chopped. Toss the vegetables with olive oil, salt, and pepper, then grill them until tender and slightly charred. Spread hummus on a tortilla wrap and layer the grilled vegetables, along with some fresh spinach and crumbled feta cheese. Roll up the wrap tightly and enjoy this delicious and nutritious sandwich on the go.
