Step 1

1 Preheat the oven to 400°F (200°C).

Step 2

2 Sauté the baby spinach until it shrinks. Salt and pepper. Place in a bowl and mix with the goat cheese.

Step 3

3 Slice the chicken breasts lengthwise but don't cut all the way through. Place in a greased baking dish. Fill the chicken breasts with the ricotta cheese mixture and sprinkle shredded cheese on top. Add dollops of the rest of the butter.

Step 4

4 Bake in the oven for about 20–30 minutes, until the chicken, is cooked all the way through. You can later pour the juices into the tomato sauce, giving it additional flavor.

Step 5

5 Fry shallot and garlic in butter until soft without letting it turn brown. Add tomato paste, vinegar, crushed tomatoes, and bring to a boil. Add the herbs and chili flakes. Let simmer on low heat for at least 15 minutes and salt and pepper to taste. (NOTE: The sauce will be enough for two batches, so freeze half of it and save for another time or use it for a low-carb pizza).

Step 6

6 Make spirals out of the zucchini, so-called zoodles, with a spiralizer. If you don't have a spiralizer you can make thin zucchini strips with a potato peeler.

Step 7

7 Fold in the zoodles in the hot tomato sauce and serve immediately with the chicken.
