These are a great replacement for burgers if you are vegetarian or if you just want a healthy, but satisfying, option.
Portobello Mushrooms with stalk removed and rinsed well
Drizzle portobellos generously with olive oil and balsamic vinegar. Then, sprinkle with garlic powder.
Grill mushrooms on both sides until they are soft and cooked all the way through. Top with your favorite cheese and melt right at the end.
Put on a really good bun with your favorite condiments and toppings (I, personally, prefer avocado and sriracha mayo!). Then eat and enjoy!
