Prepare: chop the carrots, celery and onions into uniformly sized pieces. Chop the tomatoes if using fresh, and crush or chop the garlic. Rinse the beans and measure the remaining ingredients.
Heat a pressure cooker on the saute setting. Once the cooker is hot, add the olive oil and the carrots, onions, garlic, and celery. Cook until the vegetables start to turn soft - about 5 minutes.
Stir in the oregano and hot pepper flakes, then add the pasta, tomatoes, broth and rosemary sprig.
Set the pressure to high and cook for 5 minutes.
Once the pressure cycle is complete, allow for the pressure to slow release for 5 minutes, then carefully remove the lid and stir in the spinach and beans.
Set the pressure cooker to warm until it's time to serve the soup.
