Preheat oven to 375°F and line a baking sheet with parchment paper.
In a large bowl, mash the cooked lentils with a fork until mostly smooth but still slightly textured.
Add the vital wheat gluten, finely chopped walnuts, nutritional yeast, onion powder, and Italian seasoning to the lentils.
Mix thoroughly until a dough-like consistency forms, then roll into 8 even meatballs.
Place meatballs on the baking sheet and bake for 22 minutes until firm and lightly browned.
While meatballs bake, place the white beans and minced garlic in a blender or food processor.
Blend until the beans reach a velvety, smooth consistency, adding a tablespoon of water if needed.
Warm the white bean mash in a small skillet over low heat until heated through.
Plate the warm mash, top with the lentil meatballs, and finish with a sprinkle of nutty hemp hearts.
