Pour olive oil into a wok and add the garlic slices into the cold oil.
Turn on the heat to medium-high.
As soon as the garlic slices start to sizzle, stir them constantly with a wok spatula to prevent them from sticking, and to ensure they cook evenly.
When the garlic chips turn a very light golden brown, remove them from the wok with a fine mesh strainer or spider.
Place the garlic chips on a paper towel to allow them to cool and crisp up.
Set aside 2 tablespoons of the garlic oil from the wok for the kale chips, then save the rest of the oil for another meal. Allow the oil to cool down slightly.
Drizzle the 2 tablespoons of garlic oil over the kale leaves, then use your fingers to toss the kale leaves thoroughly to coat them in the oil.
Line a baking tray with parchment paper, then arrange the kale leaves on the sheet in a single layer.
Sprinkle salt over the kale leaves, followed by the crushed red pepper.
Bake for 18 - 20 minutes or until crispy.
Transfer the kale chips to a bowl, then top with the garlic chips and more crushed red pepper if desired.
