What does "burrito" mean when it's no longer a wrapped meal?
Call it something else. Arroz con frijoles works. "burrito bowl" is like "hamburger soup."
The wikipedia page you cited literally lists burrito bowls as a variation.
I mean, if hamburger soup can be a real thing, I don't see why burrito bowls can't be.
