I made this when I was craving nacho chips with salsa and I did not have Mexican salsa or the ingredients in the cupboard. It was so different and delicious that I often make it as a starter or snack. Provided you don't eat too many tostados, it's a vey healthy dish. All authentic Italian flavour and none of the usual Enumbers and chemicals! If you don't have tostados in the cupboard, it also works very well with grissini or even wholewheat toast. If you have any left (although that's unlikely!), use it on a wholewheat sandwich with a thin wafer of Parma ham or any cheese and some rucola.
Boil the tomatoes in a pan of water for 3-7 minutes. It's ready when the peels are coming off. If you want to also make the tostados, preheat the oven on 150 Celsius.
Meanwhile, chop the onion and add it to the tomatoes.
Meanwhile, chop the basil fine. Cut the mozzarella cheese in small cubes.
Meanwhile, toast the pine nuts briefly in a pan (you don't need oil), mid heat. Keep watching, smelling and rolling them, they burn quickly.
Drain the tomatoes using a sieve so you don't loose the onion. Put it all back in the pan and add cold water. Take the peels off the tomatoes. The cold water is to stop the cooking process and to prevent you from burning your hands!
Put the peeled tomatoes in a bowl. If you like a less liquid consistency in your salsa, cut in half and squeeze most liquid out.
Add all other ingredients. Toss with a swig of olive oil, balsamico, salt, pepper and dried Italian herbs. Use a flavoured oil of your choice if you have any!
TIP - You can blend it briefly with a jar blender if you like a smoother, less chunky consistency.
TIP - If you use store-bought tostados, consider not adding any salt to your Salsa. Tostados, crisps and corn triangles are often very salty already.
For the tostados: Spread store-bought tostados on the oven rack. Sprinkle with olive oil and dried rosemary. Heat in the oven (150 Celsius) for a few minutes.
