Heat oil in a frying pan over high heat. Add onion and salt; cook, stirring often, for about five minutes, until onion has softened.

Reduce heat to medium low. Add garlic and pastrami. Continue to cook for another five minutes.

Add BBQ sauce, honey, garlic powder, and onion powder. Stir to combine. Cook for an additional two to three minutes, for flavors to meld. Set aside to cool.

Preheat oven to 375 degrees Fahrenheit. Line a baking sheet with parchment paper.

Spread dough in a thin layer on prepared baking sheet, to cover most of the pan. (It’s easiest to roll the dough between two layers of parchment paper).

Bake for 15 minutes. Remove from oven; spread mayonnaise over the surface. Top with prepared pastrami mixture. Return to oven; bake for an additional 15-20 minutes until golden and crispy.

If desired, drizzle sauce or dip over flatbread before serving.
