Generally, I’m pleased with the food I cooked during the lockdown period. It’s been varied, nutritious and enjoyable to prepare. I’ve both followed recipes and experimented, which has kept it interesting.

A tasty toasted Cheese sandwich

Cheese toasties tend to be one of my go-to snacks. Occasionally, I don’t shy from making a cheese toastie for breakfast though I tend to favour my homemade granola. More commonly they’re a dish I make when I’m looking for a quick and tasty lunch or tea. Making a cheese toastie can be tastier and significantly less expensive than ordering in food.

It’s possible to make a cheese toastie under a grill or in the oven but it’s far simpler to prepare them in a dedicated grilled sandwich maker. The Breville Deep Fill Sandwich Toaster and Toastie Maker is available via Amazon:


At present, I use a George Foreman grill. It’s simple to operate, only taking a couple of minutes to heat up, and easy to clean:

Of course, there’s plenty of debate about the best cheese for a grilled cheese sandwich. I favour using mature cheddar cheese in my toasties, because of the strong flavour and consistency. I find it melts well. If cheese oozes out onto the grill that’s a bonus as it ends up as a delicious yellow crisp.

One of my favourite cheese toasties is made with sliced ham and cheese. Known as tosta mista in the cafés and bars of Portugal, they tended to be my breakfast on the go during early starts in Lisbon. Every time I have one reminds me of a café that I used to frequent near the Santa Apolonia railway station.

Variety, though, is the spice of life. It would be dull to have the same type of toastie every time, so why not give something different a go? Those were my thoughts as I came up with this recipe.

In addition to a cheese toastie maker, you’ll need a cheese grater, mixing bowl, tablespoon, knife and chopping board to make my tuna, sweetcorn and grilled cheese sandwich.

How to make my tuna, sweetcorn grilled cheese sandwich

Making a cheese toastie is easy. Follow these four simple steps to make my tuna, sweetcorn and cheese toastie recipe:

  1. Grate the cheese into the mixing bowl. Add the mayonnaise, spice, sweetcorn and tuna fish.
  2. Chop the onion into small pieces and add them to the bowl. Stir the contents of the bowl together.
  3. Spoon the mixture onto three slices of bread. Ensure it is layered relatively thickly (see photo below for guidance). Add top slices of bread to close the sandwiches.
  4. Grill the sandwiches for around five minutes.

Hopefully, you’ll find this recipe easy to follow and the only burning issue is how to serve your grilled sandwiches. Should they be cut across the middle or diagonally? That issue has been dogging cheese toastie lovers such as myself for years. Aesthetically, I think the diagonal cut is ideal. Why? Simply because I think that diagonally cut sandwiches look better on a plate.
