Into a saucepan, add the water and the chopped chicken stock cubes, let it boil until all the chicken stock dissolves and set aside.
Spread the tomato sauce all over the bottom of a baking dish, spread evenly.
Add the pasta nets, add the soft cheese over each nest, then top it all with grated ham and grated mozzarella cheese.
Pour the water we boiled with the chicken stock into the baking dish, evenly spreading this water all over the dish.
Bake in a preheated oven at 230°C (446°F) for 25 to 30 minutes.
Top with parmesan cheese and oregano to taste, bake again for another 15 minutes.
Serve.
