Balsamic Grilled Vegetable Burgers

Author - Gena Hamshaw
Prep Time: 3 hours
Cook Time: 20 minutes
Total Time: 3 hours 20 minutes
Yields: 4 servings

Ingredients

For the marinade:

  • 1/2 cup balsamic vinegar
  • 1/3 cup olive oil
  • 2 tablespoons soy sauce, tamari, or liquid aminos
  • 2 tablespoons maple or agave syrup
  • 2 teaspoons Italian seasoning or dried oregano
  • 1-2 cloves minced garlic (optional and to taste)

For the burgers:

  • 2 large or 4 small portobello mushroom caps, stems trimmed and gills removed
  • 1 small eggplant or 1 baby eggplant, sliced crosswise into 1/2 inch slices
  • 1 large or 2 small red bell peppers, cut into 2-inch strips
  • 1 large or 2 small red onions, sliced crosswise into 1/2-inch slices
  • 4 burger buns, toasted

Instructions

  • To make the marinade, whisk all marinade ingredients together. 
  • Marinate the vegetables for at least 4 hours and up to overnight. I recommend overnight for extra flavor. You can spread the vegetables in a casserole dish or two and pour the marinade over them, flipping them to ensure that both sides of the veggies get coated. Or—my preference—marinate them in gallon sized silicone or plastic storage bags (this is especially easy if you're throwing them in the fridge overnight). 
  • Heat a grill pan over medium high heat. Remove the veggies from the marinade, reserving the marinade. Grill them for 6-10 minutes, flipping now and then so that both sides grill evenly. You can baste the vegetables with the reserved marinade every so often as you flip them. When all of the vegetables are soft and nicely grilled, remove them from heat. You may need to remove ones that cook more quickly (eggplant) before others (peppers). 
  • Alternatively, you can roast the vegetables on a foil or parchment lined baking sheet at 425F for about 25-35 minutes, flipping and basting them halfway through, or until they're tender and browning.
  • To serve, pile the vegetables on burger buns in hearty stacks. Feel free to add any condiments, herbs, greens, or garnishes you like!

Notes

Store the grilled vegetables in an airtight container in the fridge for up to 4 days.
