Eggplant and Zucchini:

1. Line a baking pan and preheat the broiler.
2. In a medium bowl, combine the coconut aminos, rice vinegar, hoisin, garlic powder and pepper. Add in the eggplant and zucchini into the sauce and mix until every piece is coated.
3. Place the eggplant and zucchini on the baking tray in a single layer, and place into the oven to broil for 7 minutes, until browned. Save any extra marinade in the bowl.
4. Remove from the oven, flip, add leftover marinade on top, and broil for 3 more minutes or until nicely browned. Be sure to check up on it often to prevent burning.
5. Remove and set aside to cool.

Onions:

1. Add 1/4 cup vegetable broth into a pan over medium-low heat. Once warmed, add in the onion and cook down, stirring occasionally, about 15-20 minutes.
2. Add more broth as needed to prevent burning, but don’t add more until it has cooked off.

Peanut Sauce

To prepare your sauce, simply whisk all of the ingredients together until smooth.

Assembly:

To prepare the sandwiches, toast the bread, then spread half of the peanut sauce on one half of each sandwich. Divide the eggplant, zucchini, onions, lettuce and tomatoes between each sandwich as desired then seal with the other slice of bread.
