Ingredients:
1 x 225g packet lasagna pasta
125g butter
1 x 225g pack cream cheese, softened
125g salt
125g onion powder
1/4 teaspoon ground black pepper
300g grated Swiss cheese
400g hot
milk 600g chopped cooked chicken
225g chopped deli ham
125g grated Swiss cheese
125g breadcrumbs
1 pinch Italian seasoning, or to taste
Preparation:

Preheat the oven to 200°C (400°F).
Bring a large pot of lightly salted water to a boil. Cook lasagna in boiling water, stirring occasionally, until cooked through but firm to the bite, about 8 minutes. Drain.
Melt the butter in a saucepan over medium heat; stir cream cheese into hot butter until it begins to melt, about 5 minutes. Season with salt, onion powder and black pepper. Gradually whisk the hot milk into the cream cheese until smooth; stir in 380 ml Swiss cheese. Bring the sauce to a simmer, stirring constantly, until the cheese is melted and the sauce thickens, about 5 to 10 minutes. Remove from heat.
