In a medium skillet start cooking the ground sausage on medium high with the oil

When that's half way done add the onions if you have peppers add it

When the onions and sausage are completely cooked fold in the spinach

This is the point where you add the red crush peppers and season salt cook till the spinach looks semi wilted

Add the leftover rice you had in your fridge

Keep cooking until the rice is heated evenly than add cheese

Remove from heat and plate. You can use it as a side dish or eat it for breakfast
