Sauce
Start by cutting the chicken breasts into strips then into cubes.
Then, transfer everything to a Zip lock bag, pour in the Coca Cola, close the bag and let everything marinate for 30 minutes.
After this time has passed, drain all the Coca Cola and transfer the chicken to a large bowl.
Season with the salt, a pinch of black pepper, the Italian seasoning, the chili flakes and mix everything very well to incorporate the seasoning.
Now, in a large baking tray, add 3 aluminum foil packets.
In each of them, add a drizzle of vegetable oil and spread it with a brush.
Cover the bottom of the foil packets with the sliced onions.
Next, top them with the potatoes cut into slices, add the chicken we prepared, dividing it equally between the foil packets, 50ml of Coca Cola into each one and set aside.
In a medium bowl, add the eggs, the milk, the salt, a pinch of black pepper and whisk until combined.
Add green onions to taste, the grated cheddar cheese, the tomato cut into cubes, the fried diced bacon and mix everything very well to combine.
Next, add this mixture to the foil packets and spread well.
Take to a preheated oven at 180° C (350° F) and bake for 35 minutes.
After this time has passed, add the grated mozzarella cheese, dividing it equally between the foil packets.
Take everything back to a preheated oven at 180° C (350° F) and bake until the cheese melts and browns.
Serve.
