Halve the sprouts and dice the pancetta.

In a medium skillet, melt the butter on medium heat until foaming. Add the sprouts and sauté for 6 minutes stirring regularly. The sprouts should be caramelised and starting to char in places. Season with salt and pepper to taste.

In a separate pan, cook the diced pancetta over medium heat for 5 minutes. Remove from heat and mix in the panko, pepper and crumbled feta.

Preheat grill/broiler on high. Place the sprouts into an oven proof dish and sprinkle over the crumb mixture. Grill on high for 5 minutes. Remove from grill and toss over mint leaves. Lightly toss then serve immediately.
