Vegan Caramelized Onion & Mushroom Grilled Cheese! Yes this is vegan, and yes this is insanely delicious! Comfort food that's healthy! Yes please. Make this dairy free nacho cheese in just 15 minutes, sauté up some onions and mushrooms, layer them on the bread, and grill to perfect. So easy and so unbelievably good. #itdoesnttastelikechicken
