Preheat the oven to 500°F (if using a baking sheet) or as high as it will go (if using a baking stone/steel; place the stone/steel in the bottom third of the oven). Let preheat for at least 30 minutes. If using a baking stone or steel, switch the oven to Broil on high after preheating.

In a small bowl, combine sour cream, mayonnaise, 2 tablespoons finely chopped cilantro, lime zest and juice, ¼ teaspoon salt, and red chile flakes. Taste and adjust seasoning if needed. Cover and refrigerate while preparing the rest of the components.

Heat a large heavy skillet over medium-high heat. Rub a little olive oil on poblanos, scallions, and unpeeled garlic cloves. When skillet is very hot, add poblanos skin-side down, then scatter scallions and garlic around them. Cook for 6-8 minutes, pressing down firmly on poblanos with a wooden spatula until skins are evenly charred.

Turn off heat and transfer vegetables to a plate. Let cool for about 5 minutes. Peel or scrape off as much of the poblanos' skins as possible, then roughly chop. Cut scallions into 2.5 cm pieces and peel the garlic.

Place poblanos, scallions, and garlic in a food processor. Add ¼ cup packed cilantro leaves, ⅓ cup crumbled feta, ¼ teaspoon salt, and a few grinds of black pepper. Pulse until finely chopped, then pour in ¼ cup olive oil and process until mostly smooth but still textured.

Stretch or roll dough into a 30-35 cm circle. Transfer to an oiled or parchment-lined baking sheet or a lightly floured pizza peel (if using a baking stone/steel).
07 -
Spread about ¾ cup of poblano pesto over the dough, leaving a 1.25 cm border. Arrange zucchini slices evenly over pesto and sprinkle with remaining ⅔ cup crumbled feta.

Transfer pizza to the oven and bake until crust is evenly browned and cheese has browned in spots—8-10 minutes on a baking sheet, 6-8 minutes on a baking stone/steel.
09 -
While pizza bakes, toast pepitas in a dry skillet over medium-high heat until lightly browned. Immediately transfer to a small bowl and toss with chili powder and a pinch of salt.

Remove pizza from oven. Drizzle or pipe crema over the top (either using a small zip-top bag with corner snipped or dollop with a spoon). Sprinkle with seasoned pepitas and remaining tablespoon of chopped cilantro. Slice and serve immediately.
