Burger Patty

Toppings

Black Olive Aioli

Sweet Potato Fries

Method

Burger Patty Preparation

  1. 1

    Prepare the Quinoa

    In a pot, combine 1 cup of rinsed red quinoa with 2 cups of water. Bring to a boil, then reduce to a simmer, cover, and cook for about 15 minutes until the quinoa is fluffy and water is absorbed. Set aside to cool.

  2. 2

    Sauté Vegetables

    In a skillet, heat 2 tablespoons of olive oil over medium heat. Add the chopped onion and garlic, and sauté until softened, about 3-4 minutes. Add the diced beets and chopped mushrooms, cooking for an additional 5-7 minutes until mushrooms are tender. Remove from heat and let cool.

  3. 3

    Mix the Patty Ingredients

    In a large bowl, combine the cooked quinoa, sautéed vegetables, beaten egg, bread crumbs, salt, and black pepper. Mix until well combined.

  4. 4

    Shape the Patties

    Form the mixture into 4 equal patties. If the mixture is too wet, add more bread crumbs as necessary.

  5. 5

    Cook the Patties

    Heat a skillet or grill over medium heat and add a little olive oil. Cook the patties for about 5-6 minutes on each side or until golden brown and heated through.

Olive Aioli Preparation

  1. 6

    Make the Aioli

    In a bowl, combine 1 cup of mayonnaise, 1 cup of chopped black olives, minced garlic, lemon juice, and salt. Mix until smooth. Adjust seasoning to taste.

Sweet Potato Fries Preparation

  1. 7

    Prepare the Fries

    Preheat the oven to 425°F (220°C). Toss the sweet potato fries in a bowl with 2 tablespoons of olive oil, salt, and paprika until evenly coated.

  2. 8

    Bake the Fries

    Spread the fries on a baking sheet in a single layer and bake for 25-30 minutes, flipping halfway through, until crispy and golden.

Assembly

  1. 9

    Assemble the Burger

    On a pretzel bun, place a cooked beet and quinoa patty. Top with crumbled goat cheese and a generous handful of mixed greens. Spread black olive aioli on the top half of the bun and close the burger.

  2. 10

    Serve

    Serve the burgers hot alongside the sweet potato fries.
