Heat the olive oil in a deep fry pan, wok or skillet over a medium high heat
Add the small bite-sized pieces of Italian sausage meat. Pan fry until golden, they will release their flavours into the oil
Add the cooked spaghetti, fry with the oil and sausage, the spaghetti will absorb the oil and flavours, you can fry for either a short time so that the spaghetti remains soft, or you can go a little longer, it will crisp up just a little
Add the frozen spinach, peas and stock, I let the veggies just sit on top of the spaghetti
Cover skillet with a lid for 2 minutes
Remove the lid, add the grated cheese and stir, so that the cheese, veggies and sausage are evenly distributed amongst the sausage
Season to taste with salt and pepper
Serve
