Pressure Cooker Tortilla Soup

Heat vegetable oil in pressure cooker over medium heat; cook and stir onions until slightly softened, 5 to 8 minutes. Add red peppers, jalapeno peppers, garlic, black pepper, and salt; cook until garlic is fragrant and onions are softened, about 5 more minutes. Stir tomatoes into onion mixture and cook until warmed, about 1 minute.

Transfer tomato mixture to a blender. Cover and hold lid down; pulse a few times before leaving on to blend. Puree in batches until smooth. Transfer tomato puree back to pressure cooker.

Stir chicken stock into tomato puree; cook and stir over high heat until just boiling, about 5 minutes. Cover and lock pressure cooker. Cook over high heat until steam begins to build and steadily escapes. Lower heat to medium-low; cook for 20 more minutes. Remove from heat; allow all the steam to naturally release. Remove lid.

Bring soup to a boil; stir in cream and cilantro. Remove from heat. Let cool for 5 minutes.

Crush tortilla chips into serving bowls; pour soup over tortilla chips. Top with sour cream and queso quesadilla.
