Preheat oven to 350 degrees Fahrenheit.

Toss sweet potato with oil and spices and place on a 9×13-inch baking sheet. Bake for one hour until the edges are browning and the potatoes are soft. Remove from the oven and allow to cool.

Add feta and mozzarella cheese to the sweet potatoes.

Fill wonton wrappers with one teaspoon of the sweet potato-cheese filling. Seal each wrapper closed using a bit of water around the edges.

Heat the oil in a deep-frying pan.

Fry the wontons for two minutes per side until golden. Remove from pan and drain excess oil on a paper towel-lined tray.

Serve warm or at room temperature with sauce (see below).

In a small saucepan, melt butter over medium-low heat. Add flour and mix until fully incorporated and turning golden.

Slowly add milk and spices and allow to thicken.

Then add the wine and simmer for an additional three minutes. If the sauce appears too thick, add more milk until it’s at the desired consistency.
