1. Cook the Barilla pasta for half the time indicated on the package. Drain pasta and drizzle with some olive oil to prevent from sticking. Place pasta flat on sheet trays or hotel pans and cool in a blast chiller. Alternatively, cool it down in a walk-in cooler. Store in zip lock bags or sealed plastic container; refrigerate and use within several hours.
2. Parcook the brussels sprouts in boiling water for about 3 minutes. Drain and shock in ice water. Halve them and season with salt, pepper, and the olive oil. Roast in a 400 degree oven until golden brown, about 15 minutes. Set aside to cool and refrigerate until needed.
3. Render the pancetta until crispy. Drain on paper towels.
