In a medium mixing bowl, whisk together the ricotta cheese and the egg until completely smooth.
Stir in the parmesan cheese, nutritional yeast, sea salt, and black pepper until well combined.
Gently fold in the whole wheat flour one tablespoon at a time until a soft, slightly tacky dough forms.
Bring a large pot of water to a gentle boil and season with a pinch of salt.
Using two small spoons, scoop uniform dollops of the dough and carefully drop them into the boiling water.
Cook the gnocchi for 2-3 minutes; once they float to the top, let them cook for an additional 30 seconds before removing with a slotted spoon.
In a large skillet over medium heat, melt the grass-fed butter until it begins to foam and turn slightly golden.
Add the fresh sage leaves and minced garlic to the skillet, sautéing for 1 minute until the sage is crisp and fragrant.
Add the drained gnocchi to the skillet and toss gently for 1 minute to coat them in the sage butter before serving.
