Yes and no.

No because most burritos are just meat and cheese, with sauce on top and beans and rice on the side.

Yes, because rice is awesome. It will absorb the sauce, so if you have your tortilla laid out, a bed of rice laid down before you put your meat down will absorb a lot of those juices that would otherwise just drip onto your plate (maybe your shirt). Also, it makes the burrito more filling.

Also no, because I can’t have too many carbs at once. The tortilla is enough. I don’t even do burritos anymore, I do street tacos. I do corn tortillas with cheese, meat, and pico. Rice doesn’t belong anywhere near that. But that’s not burritos, that’s tacos.
