I thought I'd do mustard greens myself.
So I did. Here's the recipe.
1 bunch of mustard greens from your local supermarket or farmer's market, cut into medium-size pieces, large stems removed
half of a slab of bacon, cut into smaller pieces
Smidge of red pepper flakes
Smidge of Penzey's Cajun seasoning
Salt and pepper to taste
4 cups of water
I fried up the bacon in a Dutch oven till they were little golden brown nuggets of porcine goodness and then transferred/drained them on a plate with a paper towel. After getting rid of the excess bacon grease, I dropped a good bit of the mustard greens into the Dutch oven on medium-low heat to let it mop up the crustiness on the bottom of the pan.
After the greens had cooked a bit ~ maybe five minutes ~ I put in the rest of the greens and added four cups of water into the pot. Then I added the drained bacon nuggets, red pepper flakes, cajun seasoning, salt, and cracked black pepper. Partially cover on low heat for about an hour and a half, and you have tasty mustard greens with smoky, spicy potlikker.
