Heat oil and butter in skillet over medium heat. Stir in onions and garlic, cook about 5 minutes until starting to brown just slightly.
Add peas, season with salt, pepper, a pinch of parsley and a pinch of Italian seasoning. Cover and cook until the peas are tender, about 10 to 15 minutes depending on how you like them done. I don't like mine mushy so I just cook them about 10 minutes.
When you serve them, sprinkle the cheese over top.
