How to Make It
Place ricotta and 1/2 teaspoon salt in a bowl. Using a whisk, whip until cheese is creamy, smooth, and resembles whipped cream but with a stiffer texture. Spread onto a platter to 1/2-inch thickness.
Combine tomato, cucumber, peppers, and scallions in a bowl. Stir in 1 tablespoon oil and remaining 1/8 teaspoon salt. Scatter vegetables over cheese; sprinkle with sumac and mint. Drizzle remaining 1 1/2 tablespoons oil on top. Serve with pita.
