First, you need to prepare vegetables: dice up all of them into various sizes you prefer.
Heat 1 tablespoon of olive oil on medium heat and cook the chicken until browned on all sides, about 5 minutes. Remove the chicken and set it aside on a plate.
Sprinkle the pressure cooker pot with the other tablespoon of oil and add all the vegetables (onions, carrots, celery). Cook them for about 2 minutes stirring occasionally.
Meanwhile, the vegetables are cooking, cut the chicken into small pieces. Then add the broth, bay leaf, parsley, peas, corn, salt, and pepper. Add the noodles.
Return diced chicken to the pressure cooker, lock the lid, and bring the pot to pressure on high heat. Once the pressure cooker gets at pressure, reduce heat to the lowest level to maintain thispressure and cook for 8 minutes.
When cooked, carefully open the lid, season additionally with salt and pepper to taste, serve.
