This vegan BLT is a perfect combination of marinated crispy mushrooms, tomatoes, lettuce, and a creamy Chipotle Green Onion Aioli!
Preheat the oven to 350 degrees. Line a baking sheet with aluminum foil or parchment paper. Brush some oil over the foil.
On one slice of grilled bread, spread a layer of the prepared Chipotle green onion aioli. Place a layer of crispy mushrooms on top, romaine lettuce, 4 slices of tomato, and 4 slices avocado. Spread another layer of the prepared Chipotle green onion aioli on the other slice of grilled bread and sandwich on top.
Make-Ahead Tip - Prepare the crispy mushrooms and chipotle aioli ahead of time.
