It seems rather silly to allow for a giant amount of Lemon Pistachio Pesto to go to waste. (The recipe makes a ton).
And, it also seems a bit frivolous to cook only one measly beet for a pasta recipe.
Thus, we have a combination of leftover to create something entirely new.
Smashed sweet potatoes, roasted and sliced beets, with delicious and intensely aromatic Lemon Pistachio Pesto.
Enjoy.
