Heck ya. I don't know if it's a thing people do or not but I do. I love mustard but I was raised using it pretty much exclusively on animal flesh. And mustard sandwiches. So I had all these mustards in the fridge taking up space for years after I went vegan and eventually started trying it on stuff. I think I actually started out experimenting with mustard powder to get [sulforaphane](https://nutritionfacts.org/topics/sulforaphane/) out of my cruciferous veggies but now I just squeeze a blob of mustard on my plate or on top of my sprouts and it has nothing to do with nutrition.
