Preheat oven to 350°. Prepare the garlic oil by heating the oil, garlic and pepper flakes in a small sauce pan over a medium flame. Once garlic just starts to brown, remove the pan from heat and strain out the garlic and pepper flakes.
Prepare the kale by washing and drying it (use a salad spinner). Remove the leaves from the tough stems and break them into chip-sized pieces. Place them of a baking sheet. Drizzle flavored oil over them and sprinkle generously with sea salt and pepper.
Bake for 18-20 minutes. Chips are done when they are firm and slightly blackened in places. Shave lemon zest over them and eat to your heart's content. Enjoy!
