Fortunately, I found this recipe and it's now one of our favorite things to eat along with brown rice. The greens retain their texture and the sweet/spicy seasoning is wonderful.
Collard Greens (adapted from Simply Recipes---also great for Kale)
2 lb collard greens of kale, washed well and chopped
2 T onion, finely chopped
1-2 garlic cloves, finely chopped or pressed
2 T olive oil
2 T sesame oil (optional--tastes great with or without)
chili pepper flakes (I like this on the spicy side, and use about 1 T)*
salt (1-2 tsp)*
sugar (1-2 tsp)*
*The last three ingredients can be varied according to your taste. You'll find the right balance the more you make this dish.
In a big pot with a lid, heat the olive oil and saute onion and garlic for about a minute. Mix in the greens and remaining ingredients. Cover, turn the heat to low, and cook for 8-10 minutes. Stir, and serve.
