Be sure to stir this mixture every few minutes and continue to cook until the peppers and onions and soft but not mushy. (Approximately 20 minutes) Add the mushrooms and cook for 5 more minutes. and then add the spinach and tomato sauce and just cook till warmed through and spinach is wilted. Squeeze 1/2 lemon over peppers and onions. and remove from heat.
Slice your fresh Italian Sub-Rolls in half lengthwise and slice your sausage in half lengthwise too so it stays on the bun better place your sausages into the fold. Top with enough filling to fill the bun. Go ahead and make them messy, they're more fun that way!
