Taquitos come the closest I can think of...
Seasoned shredded roast rolled in corn tortilla and deep fried. Dip in guac, sour cream and salsa. TDF
(there are frozen variations at Sam's Club that can be done in the oven. The beef one is pretty good in a pinch!)
Enchiladas are so soft I can't think of a way to do those appetizer style. You might do quesadillas, though. Pan fried flour tortillas with cheddar and jack melted inside (either folded and rolled or flat and cut into wedges) in which you can add slices of avocado, salsa, etc, or dip the wedges into it.
