Cook quinoa according to package. While quinoa is cooking, wrap sweet potato in damp paper towel and microwave for 5 minutes or until you can easily pierce it with fork.

Preheat oven to 350 degrees F and line baking sheet with parchment paper. Allow sweet potato to cool before handling, then remove skin and place in large mixing bowl. Add black beans and mash together.

Add chia seeds, cooked quinoa, garlic, onion and taco seasoning. Mix until all ingredients are equally distributed.

Scoop 2 Tbsp. veggie burger mixture, roll into ball then place on parchment. Gently press down to flatten and repeat with remaining mixture, spacing each burger 1/2-in. apart. Bake for 5 minutes, flip, then bake for another 5 minutes.

Line another baking tray with parchment paper and heat butter. Cut Hawaiian rolls in half then add bottom layer of slider rolls to parchment.

Once veggie burgers are cooked, place each slider on bottom layer of Hawaiian rolls. Add cheese on top of buns. Pour melted butter over and sprinkle with chopped parsley. Bake for 10 minutes. Serve and enjoy.
