Preheat the oven to 180ºC.

Mix the oats, tomato sauce, olive oil, spices, and yeast.

Put half of the mixture in an ovenproof bowl; then add in half of the cheese. Pour the rest of the mixture on top and sprinkle on the remaining grated cheese.

Garnish with the tomatoes and bake in the oven for 25 minutes. For the last 10 minutes set your oven to the gratin function.

Remove from oven and sprinkle on some yummy Kale Chips.
