Split Pea and Sweet Potato Burgers with Caramelized Onion and Feta Aioli

For the burgers:
Bring broth to a boil in a pot, then add split peas. Reduce heat to medium and cook for 45-60 minutes, or until peas are softened. Drain off the broth.

While peas cook, bring a large pot of water to boil. Add cubed sweet potatoes and cook for 12-15 minutes or until soft. Drain.

Add sweet potatoes into a large bowl and mash well. Add the split peas and mash gently (try to not break up all of the peas). Stir in remaining burger ingredients, except the oats and oil. Add oats last, starting with 1/3 cup, then adding more if the mixture is too wet. Cover bowl and place mixture in the refrigerator for two hours.

Once cooled, form 12 patties from the mixture, each about 1/2″ thick and 4-5″ wide.

To cook: Heat 2 teaspoons of olive oil in a large non-stick pan over medium heat. Place 2-3 patties in the pan and cook for 5 minutes per side, or until golden brown. Transfer to a plate and cover to keep warm while you cook the remaining patties (add 2 teaspoons olive oil to the pan before you cook each batch). Serve warm topped with aioli and other toppings of choice on a soft bun.

For the aioli:
Heat a non-stick pan over medium-high heat. Spray with olive oil spray, then add garlic and onions. Saute for 4-5 minutes, then sprinkle with brown sugar. Cook for 3-4 additional minutes, stirring frequently. Remove from heat.

Add onion mixture to a small food processor and pulse to combine it with the mayo and feta. Season with salt and pepper to taste. Serve immediately on burgers, or cover and refrigerate until ready to use.
