Vegetarian Black Bean and Rice Burgers

1/2 can black beans, drained and rinsed
1/2 cup microwaveable brown rice
1 shallot, finely diced
1 tbsp salsa
1/8 cup plain Greek yogurt
1/8 cup salsa
2 hamburger buns

Use a fork to mash the black beans into a paste.
In a medium bowl, combine the beans, rice, shallot, and 1 tbsp salsa.
Stir together until fully combined.
Divide the mix into two equal balls. Spray a skillet with cooking spray and heat over medium-high heat. Place the two balls in the skillet and flatten into a patty with a spatula.
Cook for 4-5 minutes on each side, until light brown and crispy.
While the burgers cook, combine the Greek yogurt and salsa in a small bowl and toast the buns.
Place the patties on the buns and top with the sauce.
