Preheat your oven to 425°F for the fries and prepare a baking sheet lined with parchment paper.
In a bowl, mash the drained black beans until mostly smooth. Stir in rolled oats, egg white, nutritional yeast, diced red bell pepper, smoked paprika, cumin, salt, and pepper to create a cohesive burger mixture.
Form the mixture into a patty shape.
Lightly oil a non-stick skillet over medium heat and cook the black bean patty for about 4-5 minutes on each side until it develops a crisp exterior.
Meanwhile, peel (if desired) and cut the sweet potato into fries. Toss the fries in olive oil, smoked paprika, salt, and pepper.
Spread the fries evenly on the baking sheet and bake in the preheated oven for 20-25 minutes, turning once halfway through, until they are crispy and tender.
For the tangy dip, mix nonfat Greek yogurt, lemon juice, garlic powder, and a pinch of salt in a small bowl.
Plate the black bean burger with a side of crispy sweet potato fries and serve with the Greek yogurt dip. Enjoy while warm!
