Technically, maybe. But it was a regular round burger, not loose ground beef or some torpedo shape. Tortilla on plate. Onions and mushrooms on tortilla. Cheeseburger upside down on top. Then I sliced the outside edge of the tortilla, kind of like a sun pattern, and pulled the flaps up over the burger. Seared it on the pan to keep the flaps closed. So the end result was actually the shape of a hamburger. Dipped it in ketchup. It was more like substituting a tortilla for a bun than a burrito IMO. But yeah, I guess a burrito .

More accurately, the leftover buns we had were discovered to be growing mold. My wife asked if I wanted to go buy buns and I said no. She said "well I'm fine just eating it without a bun so I don't care, but I know you do". Necessity is the mother of invention .
