Press Saute and add a little olive oil. While the oil is heating, julienne the onions and slice the garlic and add to the pot.
Sauté the onion and garlic about 5 minutes, until the onion is translucent. Then add the crushed tomato, a little oregano, freshly ground black pepper and salt. End Saute, cover the pot, and cook on High Pressure for 10 Minutes.
Once the time is up, let the pot depressurize naturally (or do it manually). If the sauce is too runny, which is likely, you can press Saute to reduce it a bit. It’s time to enjoy!
