Portobello Sliders with Caramelized Onions

What you will need ( sandwich ):
4 ciabatta dinner rolls (or slider buns), toasted
2 large portobello mushrooms, sliced into thin strips
a large handful of mixed greens
1/2 medium white onion, sliced into rings

What you will need ( marinade ):
1/4 cup white cooking wine
2 tbsp balsamic vinegar
1 tbsp olive oil
2 cloves garlic, crushed
1 tbsp olive oil
salt and pepper

What you will need ( basil aioli ):
1/4 cup vegan mayo
2-3 garlic cloves crushed
4-5 basil leaves, minced

Steps to yummy goodness:

  1. Mix together the ingredients for the marinade in a flat, shallow dish and submerge the portobello slices completely. Allow mushrooms to marinade for at least 30 minutes.
  2. Meanwhile heat 1 tbsp of oil over medium heat. Add sliced onions and reduce heat to low. Saute for 5-10 minutes until golden and caramelized. Remove onions from heat and set aside. Place portobellos with marinade into hot saute pan. Turn up heat and bring liquid to a simmer. Heat until liquid is reduced and mushrooms are browned and cooked all the way through.
  3. In a small bowl mix together the ingredients for the basil aioli.
  4. Now it’s time to assemble the sandwich!
  5. Spread the basil aioli on the bottom side of all four buns. Evenly distribute greens, portobello, and caramelized onions. Top with the other half of the bun and serve immediately
