Place the ribeye steak on a sheet pan and set it in the freezer for about 10 minutes until very cold, but not frozen. Trim excess fat from the edges, then slice the steak as thinly as possible using a sharp knife. Season the sliced steak evenly with kosher salt and black pepper.

In a large skillet over medium heat, add 1 tablespoon olive oil. Add sliced onions, green bell pepper, and red bell pepper. Season with 1/4 teaspoon salt and pepper. Cook, stirring occasionally, until the vegetables soften and caramelize at the edges, about 12 to 15 minutes.

Heat a griddle or large skillet over medium-high heat. Add the remaining 1 tablespoon olive oil and the seasoned, sliced steak. Distribute the steak in a thin, even layer. Cook for 1 to 2 minutes, then stir and cook for an additional 1 to 2 minutes until just cooked through.
