Instructions
- Caramelize the onions by heating 1 tablespoon of olive oil in a large skillet over medium heat. Add onions and sauté until caramelized and tender - about 25-30 minutes, making sure to stir frequently. Season with sea salt to taste. Set aside when finished.
- Meanwhile, marinate the mushrooms in a large zip-lock bag for 15-20 minutes before cooking.
- Also make the aioli while the onions are cooking, by combining the roasted garlic with mayonnaise then season with sea salt and freshly cracked pepper, to taste; mix well and set aside to allow the flavors time to mingle
- Cook the portobellos by heating the remaining olive oil in the same large skillet over medium heat. Once the skillet is hot, place the mushrooms in, top side up. Cook for 4-5 minutes then flip.
- Pile the caramelized onions onto the mushroom then place Havarti cheese and cook for an additional 3-4 minutes.
- Serve by spreading the garlic mayonnaise on each side of the toasted bun, add the mushroom then top with tomato slices and basil. Enjoy!
