These are almost crazy how easy these are. You almost don't need a recipe. Just a nice hot pan!
I usually count on serving about 5-6 sprouts per person.
Trim and slice the brussels sprouts - either a knife is fine, but a mandoline makes it quick.
Heat your cast iron pan over medium high heat and add about 1 Tablespoon of olive oil.
Add your sprouts and don't stir them right away. Take this time to grab a lemon and zest it over, as well as add about 1 teaspoon of chilli flakes, salt and pepper. Now stir. There will be some nice charred brown bits and steamed goodness in there. Add juice of 1/2 of the lemon and stir again. They should be about done now. Taste for seasoning and serve. Give them a try!
