Preheat oven 300 F.
Remove ribs from one head of kale. Break the large leaves into quarters (3-4 inches).
Toss in a bowl with:
1 1/2 tablespoons olive oil
1 tablespoon soy sauce
Roast on rimmed baking sheets for 13 minutes, then turn pan.
Sprinkle with sesame seeds and bake 5-7 minutes more (until leaves are crisp but not brown).
Stir half way through cooking.
If not crisp enough, return pan to oven for 5 or more minutes.
