Preheat oven to 500 degrees Fahrenheit.

In a bowl, toss chickpeas with plum sauce until evenly coated.

Set aside the chickpea mixture to allow flavors to meld while preparing other ingredients.

Thinly slice the red onion, yellow pepper, and red pepper.

Spoon the chickpea and plum sauce mixture evenly over the prepared pizza crust, spreading to the edges.

Sprinkle red pepper flakes over the plum sauce to taste, considering the heat from the peanut sauce.

Layer the thinly sliced red onion, yellow pepper, and red pepper over the chickpea and plum sauce mixture.

Reduce the oven temperature to 450 degrees Fahrenheit.

Bake the pizza for 12-13 minutes, or until the crust is golden brown and the vegetables are tender.

Remove the pizza from the oven and drizzle peanut sauce evenly over the top.

Garnish with thinly sliced green onions and chopped cilantro.
