Preheat oven to 375 °F and line a baking sheet with parchment paper or aluminum foil.
Toss kale pieces with olive oil and salt and spread evenly across sheet. Roast in oven for 10-15 minutes, stirring once while cooking. Chips are done when kale pieces are crispy and lightly browned on the edges. Serve as is or toss with spice blend of choice.
