Pre-heat oven to 375°F, 190 c, gas mark Drain the can of salmon.
Flake the fish.
Mix with the cheese, onions and red pepper.
Set aside.
Put the flour into a bowl, add the eggs, salt and basil.
Mix well to form a soft dough.
Divide into egg size pieces.
Knead until smooth.
Roll the dough pieces on a lightly floured board to a maximum 2mm / 1/10 inch thick or roll each piece through a pasta maker reducing the setting to 5 or 6 over 3 or 4 rollings.
Cut the pasta sheets into 3cm / 1 ½ inch squares.
Put salmon filling onto one corner of each square then fold in half diagonally to make a triangular "pattie".
Dry on silicone paper for 1 hour before cooking, turning each pattie over after 30 minutes to dry undersides.
Put the soup into a casserole dish and drop the salmon patties into it.
Cover with a lid and cook in the oven for 30 minutes.
