1. Preheat broiler and toast baguette, taking great care not to burn them (the toasting doesn't take long and they can burn easily so be careful!).
2. In a small bowl, add vegan mayo. Squeeze garlic into the mayo with a garlic press, and add lemon juice.
3. Spread the garlic aioli onto the sourdough toasts. Top each piece of toast with a slice of avocado and serve!
I have gotten very good feedback from my extremely veg-phobic family. They usually won't try anything vegan, but everyone gobbled these up with alacrity!
