An easy tomato sauce recipe to make in the microwave.

Slice one onion and put it in a microwaveable dish. Add one tablespoon of olive oil and microwave on high for three minutes.

Add one tin of chopped tomatoes, some tomato puree (one tablespoon or one of those little tins). If you don’t have tomato puree, ketchup is fine but not too much. If the tinned tomatoes are budget supermarket ones, add one tsp sugar. Add pepper, salt and herbs (basil is good) and microwave for three more minutes.

If you have a hand-blender, “zuzz” the mixture until it is coarse rather than actually chunky. Leave to stand as long as you like, then when you are serving up the food, pop it back in the microwave for another minute.
