Ingredient Notes & Substitutions
- Spaghetti Squash: Spaghetti squash is a fun type of squash named because the tender part of the squash looks like spaghetti. They are in season late summer and early fall, so buy them when they're fresh!
- Mushrooms: I used cremini mushrooms (also known as baby bellas) because they have more flavor. White button mushrooms work just fine too!
- Broccoli: I like to buy the broccoli crowns to maximize the ratio of florets to stems, but you can and should eat the entire stalk of broccoli, including the stems - just cut off the tough exterior
- Salt & Pepper
- Vegan Parmesan: head over to this post for notes and full instructions.
