Preheat the oven to 200°C/400°F.
Cut the tomatoes, peel and cut the onion and cut the garlic. Bake the onion and garlic in a pan on a low heat and add the tomatoes and the herbs. Now bake this on a medium heat until the tomatoes are softened. Poor everything in a (measuring) cup and puree.
Now add the package 'Pulled Oats' Tomato and mix it all together. Set aside.
Cook the shells 'al dente' in some water and a small splash of olive oil and salt. Drain them, wash with cold water and let them cool down.
Now fill the shells with the pasta sauce and put them all in an oven scale. Sprinkle some vegan mozzarella over them. 25 minutes in the oven.
Serve with some fresh herbs!
