While dough is rising, preheat oven to 400 degrees F (200C). Line a baking pan with foil (or simply grease if preferred) and spread peach slices, onions, and almonds out evenly. Sprinkle with salt and pepper and drizzle with olive oil and about 3 tablespoons balsamic vinegar. Roast in oven for 20 to 25 minutes, stirring halfway, until the peaches and onions start to darken and smell amazing. Remove from oven and let pan cool for a few moments while you prep your crust. Roll the pizza dough out into a circle that's roughly 1/4 inch thick and dust a pizza pan with flour or corn flour and place crust on pan. Spread marinara sauce and sprinkle cheese an an even layer. Top cheese with your roasted peaches, onions, and almonds. Sprinkle with a bit more balsamic, salt, pepper, and about half of the cilantro.
