A 20 minute healthy after school snack. I even like them cold from the fridge. Feel free to add meltable vegan cheese before the final bake. Although I am perfectly happy with the cheesiness of nutritional yeast.
Heat your oven or toaster oven to 400 Fahrenheit. Slice your sweet potatoes thinly to just under a half inch thick. I cut my into small rounds cause they are cuter that way but cut them the long way if that floats your boat.
Arrange them in a single layer on a baking sheet. Bake for ten minutes. Flip them and bake another ten minutes.
Now smear the tops of each with a smear of marinara and then top with a smear of pesto and a sprinkle of nutritional yeast.
Bake another 5 minutes until slightly tender but retaining the structural integrity to hold together and be eaten like a slice of pizza.
