Begin by rinsing collard greens well and shaking off excess water, but do not pat dry. Continue slicing the thickest part of the stem from each leaf off with a sharp chef's knife.
You can also pull the leaves off the stem as you go to speed things up, slicing off any dark green pieces and adding them into your pile for cooking.
You do not need to get rid of stems entirely, but should remove most of stem, as it can be tough and bitter.
You should have a nice little pile of greens now. Pile them together, and begin slicing into small 1/4 inch strips. You can definitely go smaller here, but I get lazy on occasion.
Continue slicing lengthwise, then simply slice the piles of strips crosswise.
You will finish up with a lovely little pile of collard green bits. Just dice up any larger stray pieces.
Dice up some garlic. Adding a few steps here in case you have never diced garlic. Take a few cloves and place on cutting board, skins on.
Press down firmly with palm of your hand and the flat part of a chefs knife
Remove the skins from the now pressed cloves. They will be easy to remove now.
Then simply dice crosswise and lengthwise with the knife, keeping your fingers curled inward with knuckles against the knife to avoid cuts.
Add the greens to your stainless steel or metal pot. You can probably use non-stick, but the stainless steel gets a great sear. Add the garlic, olive oil, salt, pepper, and crushed red pepper flakes and toss well with a wooden spoon. Wait to add the vinegar until heated. Turn the burner to high heat and cover.
After a few minutes on the heat, remove lid and stir with wooden spoon. Let them cook for about 6-8 minutes until nicely wilted. You can cook longer if you like them less firm. Uncover and remove from heat. Serve with love.
