SEASON the ribeye with salt and pepper and cook to desired level of doneness. (About 3-4 minutes per side for medium, depending on the thickness of the steak.)
REMOVE the steak from the pan and let rest.
WHILE the steak rests, heat the ghee in the same pan, add the veggies, season with salt and Italian seasoning, and sauté for 5-6 minutes, until softened and lightly browned.
SERVE the veggies over the steak.
Notes
Note: Slice the veggies very thin (¼” or less) to ensure a quick cooking time (a mandolin is great for this).
