Cook pasta according to box directions in a large pasta pot.

Drain and stir in olive oil to keep from clumping; set aside.

Transfer Bruce’s Yams Cut Sweet Potatoes, melted butter and evaporated milk to a medium saucepan. Bring to a slight simmer then add all three cheeses.

Cook, stirring frequently, over medium-low heat until cheese has melted.

Pour over the pasta and mix well to incorporate.

Before serving, sprinkle with salt-free seasoning.
