To substitute for mashed potatoes, I’m making a cauliflower mash. You can’t boil the cauliflower to make the mash or else it gets way too soggy and yuck.
Here’s what I do:
Cut the head of cauliflower into florets.
Put into a microwave-safe dish with about 3-4 tbs of water. Cover. Microwave for 3 minutes and stir. Microwave another 2 minutes. Check for softness. If not soft, microwave another minute or so.
Mash with a potato masher, or my favorite, the stick blender.
Add salt to taste and some coconut milk for creaminess.
