I was about to give slow-cooker spaghetti a try and got idea eruption. I replaced the spaghetti with frozen O'Brian potatoes, combined the other ingredients and kept adding additional potatoes to achieve the right balance of sauce. I always make 'garden spaghetti sauce' adding planned or on hand veggies. This time broccoli and frozen corn for color. I know you're wondering how it turned out. It was very good and I'll make it again. Sorry about 'the plating' but didn't think to photograph until this morning so you get leftovers. Details, 24 oz pasta sauce, frozen O'Brian potatoes with onion and bell pepper, whatever additional spices and ingredients that strike your fancy. Instant Pot on Slow Cook set at More for 3 hours. Then Keep Warm for another 3 hours. ** Instant Pot Slow Cook set on More is 180°-185° F on my IP. **
