Put the gelatine sheets in a bowl and cover with cold water. Meanwhile, boil some water in a saucepan with 1 sprig of fresh mint and then blanch, for 3 minutes, the courgettes cut into rounds of about 3 mm thick. Drain the courgette and cool them in pre-cooled Freddy with the function of blast chilling for about 20 minutes.
Cut the red pepper into cubes and cook in a pan with a little oil, salt and pepper for about 10 minutes, then let it cool in Freddy together with the courgettes. Pour a few slices of courgette seasoned with salt, pepper and oil in 4 glass jars (for example yogurt jars), add a tablespoon of cheese, aromatize with the remaining chopped mint, add other slices of courgette. Pour a little more cheese and repeat the operation until filled in the jar. Do the same in other jars using peppers and tomatoes instead of courgettes.
Place in pre-cooled Freddy jars with the function of blast chilling for 45 minutes so that the cheese will curdle, cover them with plastic wrap and store them in the picnic basket no to use.
