Preheat your oven to 350°F.
Slice the zucchini in half lengthwise. Using a mandolin or a peeler and applying steady pressure, create long, thin slices from the cut side of each zucchini. If you don’t have a mandolin or peeler, use a sharp knife to make thin, flexible slices.
In a food processor or blender, combine the white beans, basil, lemon juice, nutritional yeast, and garlic. Pulse until smooth. Taste and season with black pepper as desired.
Lay the zucchini strips flat on a cutting board and spread each strip with about 1 tablespoon of the white bean mixture. Roll them up and place in a casserole dish. Once all the zucchini roll-ups are in the dish, cover with the tomato sauce.
Bake uncovered for 30 minutes. Remove from the oven, divide between plates, and enjoy!
