Prep the Instant Pot: Turn on the Instant Pot and set it to the "Sauté" function. Add the olive oil and let it heat up.
Sauté: Add the chopped onion, garlic, green bell, and sofrito to the Instant Pot. Sauté for about 3-4 minutes, until the vegetables are softened and the onion is translucent.
Add the Ham and Vegetables: Stir in the diced ham, carrot, olives, and potatoes. Cook for another 1-2 minutes, allowing the flavors to meld together.
Incorporate the Spices: Sprinkle in the adobo, Sazon, oregano, Stir everything together to combine.
Pour in the water: Carefully pour in water up until a 1/2 inch from the PC Max line. Give the mixture a good stir, ensuring all ingredients are well combined.
Pressure Cook: Cancel the "Sauté" function. Secure the lid on the Instant Pot, make sure it's sealed, and set it to "Pressure Cook" (or "Manual") on high pressure for 8minutes.
Quick Release: Once the cooking time is up, perform a quick release by carefully turning the pressure release valve to the venting position. Wait for the steam to escape completely and the pressure indicator to drop before opening the lid.
Cook the Noodles: Switch the Instant Pot back to the "Sauté" function. Add the noodles & fresh cilantro to the pot and let them cook for about 5-7 minutes, or until tender.
Season to Taste: Taste the soup and add salt and pepper as needed. If you prefer a bit of acidity, squeeze in some fresh lime juice.
Serve: Ladle the hot soup into bowls. Garnish with fresh cilantro if desired and serve with lime wedges, tostones, or avocado on the side.
