The tomato sauce used in this recipe is a goodie and can be used as a simple pasta sauce, a base to which to add minced meat for a lasagne, or layer a mix of cooked vegetables through it, cover with grated cheese and breadcrumbs and bake off as a gratin.
For this stack I used diced fresh tomatoes but canned works better when tomatoes are out of their natural season.
1 Dice an onion, chop a few garlic cloves and cook in a little olive oil to soften.
2 Add a good amount of tomato paste and fry in the oil.
3 If you have it, add some sprigs of fresh thyme or a little dried thyme.
