Florida Orange Juice with Sweet Potato & Chickpea Burgers with Tangy Orange Sauce

To make the sauce:

1. Place the orange juice, mustard, horseradish, mayonnaise, and garlic in a small bowl and whisk to combine.
2. Cover and refrigerate until ready to use.

To make the burgers:

1. Heat the oven to 400 degrees F.
2. Place 2 cups of the orange juice and water in a small saucepan, set over high heat, and bring to a boil. Add the rice, cover, and reduce the heat to maintain a bare simmer. Cook until the rice is tender, 55 to 60 minutes.
3. In the meantime, place the sweet potatoes, chickpeas, and remaining 1/2 cup orange juice in a small baking dish. Cover and roast until sweet potatoes are tender, 35 to 40 minutes.
4. Transfer the potatoes and chickpeas to a food processor and process until somewhat, but not completely smooth. Transfer the mixture to a large mixing bowl and add the rice, breadcrumbs, salt, cumin, garlic powder, and coriander. Stir to combine. Cover and refrigerate for 1 hour. Shape the mixture into 6 patties.
5. Place 1 tablespoon of grapeseed oil in a large sauté pan, set over medium heat, and when the oil shimmers, add the patties. Cook for 4 to 5 minutes or until browned. Add the remaining tablespoon of oil to the pan and carefully flip the patties. Continue cooking until heated through and browned, about 3 minutes.
6. Serve burgers topped with sauce and garnished with arugula and onion.
