Gratin chicken medallions

Ingredients
1 packet Granja del Sol Chicken Medallions
3 Tbsp. sunflower or corn oil
½ packet chopped onion
½ packets Granja del Sol Spinach
1 cup white cream sauce
2 Tbsp. grated parmesan cheese
Pepper to taste
Salt to taste
Directions
In a preheated oven, half bake the Granja del Sol Chicken Medallions in an oven sheet without adding any grease. Stir fry the onion in a heated saucepan with a bit of oil.
Once it gets transparent, stir the Granja del Sol Spinach in, cook it for a few minutes more and then turn the heat off.
Once it is warm, mix it with the white cream sauce and the grated parmesan cheese. Add pepper and just a pinch of salt as it includes parmesan cheese. Pour part of the filling over the chicken medallions and cook au gratin.
