Set an iron skillet or a frying pan over medium heat. (Iron skillet preferred)
Drop a tablespoon of butter to melt.
Divide up the prepared dip evenly over each flour tortilla.
Transfer one tortilla to skillet, toppings-side-up.
Cook for 30 seconds, or until heated through.
Using a spatula, fold one side of the tortilla over the other.
Cook for a few more seconds, or until it starts to sizzle; flip it over and continue to cook just until lightly browned.
Remove from skillet and transfer to a paper towel-lined plate.
Continue to cook the rest, adding more butter as needed.
Cut each prepared tortilla in half and serve immediately.
