Clean and wash the tomatoes. Grate them to remove the skins or pass them through a manual food grinder. Wash the peppers, bake and peel them. Put the tomatoes in a pot on the stove.
Pour oil and salt to taste and leave to boil, stirring periodically, then remove from the stove.
Once cooled a bit, fill the jars with it, close and put to boil again. After boiling for 5 min., take them out and flip upside down. Flip right-side up once cooled.
It's the perfect pickle to enjoy during winter whenever you don't have time to cook.
