What food group is mustuard?

Mustard is a bit tricky! It doesn't fit neatly into one food group because it's technically a condiment, which is a category of its own.

However, if you're trying to categorize it for dietary purposes, you can consider it a vegetable (specifically a seed) because the mustard seeds are what give it its flavor and color.

It's also important to note that mustard often contains vinegar, which would make it a fruit in some sense, since vinegar is made from fermented fruit.

Ultimately, it depends on how you're using it and what you're trying to accomplish with your dietary choices.
