A passage from Wild Edible Plants of New Mexico:

Tumble mustard is a little more coarse and hairy than London rocket (Sisymbrium irio), a lower elevation Mustard species. However, once cooked, differences between the two plants are minimal.

For the dedicated, the small seeds can be used as a Mustard seed replacement; however, they are very tiny and may not be worth the effort. For this use, Jewel flower is a better plant.
