Step 1

You will need a dish approximately 30 x 23 cm or 9 x 12 inch. Mine is square. Grease with oil or butter. You'll also need a fry pan

Step 2

Set the oven to 190 C / 360 F.

Step 3

Start by making the egg frittata mixture. Heat a fry pan on medium and add the olive oil then the onion and saute till softened. Add the oregano, add red pepper and corn and saute for a couple of minutes without colouring before adding the chickpeas. Stir well.

Step 4

Pour the vegetables into the baking dish you prepared earlier

Step 5

Beat the eggs, milk, tomato sauce and salt and pepper together till well combined and pour over the vegetables spreading flat.

Step 6

Bake the frittata till just firm. Check at 15 minutes and leave in for longer if still not completely set. Depending on your oven it could take 15-25 minutes. (my oven is slow and not fan forced)

Step 7

Take the egg out and set aside to cool while you prepare the bread. Cut all the rolls down the middle and open them.

Step 8

Pile the slices of ham onto each roll. Top with grated cheese and then a slice of frittata. You should get at least 12 squares from your dish (23 x 30 cm). Measure them out evenly before slicing into squares.

Step 9

Once filled put the top on the sandwich and wrap in baking paper and then foil.

Step 10

The sandwiches can be popped into the oven in the foil and paper jacket once defrosted for a few hours. This is my favourite way to eat them. When you open them the cheese is melted and hot.They are also fantastic defrosted and popped onto a sandwich press unwrapped.They can also go into a fry pan to be toasted on both sides with the foil on. this saves on washing up. If you need to microwave them, take out of the foil and unwrap a bit before microwaving. This method will give you a very soft melty roll if that's your thing
