Notes
I did not add the time that it takes to make the sausage and gravy. But my recipe for it takes 26 minutes to cook plus the time it takes for the pressure cooker takes to come to pressure and release the pressure.Helpful tips
Instead of slow cooking the red gravy and sausage, you can instead use a pressure cooker. Here is an easy spaghetti sauce with sausage recipe so I won't explain how to cook that again here.
You can make the sausages and gravy a day or two before.
Slow cooking causes the sausages to be soft, juicy and succulent but so doesn't pressure cooking them. :)
You can use any cheese you prefer on top of the sub, but I love how muenster tastes so that's what I used.
