This recipe is a knock-off of one that was served in a restaurant I used to work in. They served their tacos in oniony tortillas (cakes?), but the regular flour tortillas are similar. This is one of the many ways I use up leftovers.
Stirfry julienned carrots and onion, sliced portobello and leftover pork or chicken. Toss w hoisin sauce and serve w flour tortillas. Serve w garlicky fried rice.
