Heat the olive oil in a skillet over medium heat. Add the crushed red pepper, kale, and grape tomatoes then cook, stirring occasionally, for 2-3 minutes. Add the garlic and continue cooking, stirring constantly for 1 minute. Season with sea salt and freshly cracked pepper, to taste. Add 1-2 tablespoon of water to the skillet then cover with a lid; steam for 1-2 minutes. Remove the lid and taste; re-season if needed then sprinkle with shaved Parmesan if desired. Serve immediately. Enjoy.
