Pesto is delicious, but store-bought versions often include cheese, and it can be pricey to make your own with fresh basil and pine nuts. Spinach is a great stand-in for the bulk of your pesto, as it is less expensive than fresh basil. I also use pumpkin seeds as a more economical option to pine nuts, and nutritional yeast for the cheesy flavor.
If you prefer a softer garlic flavor, when you have the oven on for something else (between 350°F and 400°F), put some garlic cloves, in their skins, in a small oven-proof dish and bake for about 10 minutes, until soft. Squeeze them out of their skins to use—they’re great spread on bread or mashed into potatoes.
