In a microwave-safe bowl (or Mr. SuzerSpace's favorite - a coffee cup) combine turkey, sauce and olive oil. Stir to combine.
Cover bowl/cup with a spatter shield and microwave on high for 30 seconds. Stir, and then heat again for 20 seconds more. The turkey is pre-cooked so you just want to heat it and the sauce to eating temperature.
Sprinkle black beans on flatbread, top with cheese (if desired) and Turkey/sauce mixture. Top with arugula if desired
