Dice the smoked sausages into large chunks. If using Italian Sausages do not dice them now.
Set the Instant Pot on SAUTE and add olive oil. When the oil becomes moderately hot add the sausages and brown them well. Do not worry about the bits and crumbs browning at the bottom of the Instant Pot. We'll be de-glazing it later.
Set aside the browned sausages. If using Italian Sausages Brown them whole and than dice the,. It's easier this way.
Next, add the sliced bell peppers, onion and garlic in the Instant Pot and saute for 1-2 mins.
Add the Rotel diced tomatoes, tomato paste, all the seasonings, salt and the red wine. Give everything a good mix and de-glaze the pot very well so that there are absolutely no bits and crumbs stuck at the bottom of the steel pot of the Instant Pot.
Close the lid, Seal the Valve and PRESSURE COOK on HIGH for 10 mins.
When the cooking cycle is over the Instant Pot will make a beeping sound. Do a Quick Pressure Release immediately by moving the valve from the SEALING to the VENTING position.
Open the lid slowly and throw back the browned sausages to the pot.
Cook down the sauce until it reaches your preferred consistency. Simmer it on SAUTE kept at LOW for few mins. Sometimes the peppers releases a lot of moisture and cooking down the sauce is the best remedy to this :)
Enjoy the delicious Instant Pot Sausage and Peppers either on a bed of rice, quinoa, pasta. Or stuff them to make Hoagie rolls or sandwiches.
