Open Faced Tuna Melt Sandwiches

I’ve been wishing, and hoping, and thinking, and praying, and planning, and dreaming, etc., of the day when I could incorporate fish into our meal plans at home. And, I’m sorry I had to steal the opening line from Dusty Springfield’s song to drive home my enthusiasm.

2019 has been a year of firsts when it comes to new weeknight dinner options at the Thomas-Ewing household. Before I get any further into this discussion, let me just say that everyone is entitled to their own choices when it comes to their personal diets – be it vegetarian, vegan, or otherwise.

But, if – like me! – you’re the person responsible for putting a meal on the table every night, the one that’s responsible for meal-planning, grocery shopping, making sure the pantry and fridge are both stocked, and that everyone has the right drink, the right snack, and something to take for lunch every day, then my decisions trump your dietary restrictions. Period.

For the past eight years, I have lived with John.e’s vegetarianism. Then, three years ago when McKenna came to live with us, I had to live with her vegetarianism too. I started to crack! I cannot tell you how many times all three of us talked about ideas for meals and ways to lighten the burden. But, none of them worked, because nobody followed through.

When McKenna started to eat meat on Christmas day last year, it was the best gift a daughter could ever give a dad. Not because I disapproved of her choice to be a vegetarian in the first place, but because as a food blogger, who does not specialize in vegetarian recipes, it was rather difficult.

Then, when I prepared a few fish dishes for Lord Byron’s Kitchen back in 2018 and John.e actually ate some of them, I rejoiced! I was able to add some seafood back into our meal options. As long as I didn’t make shrimp, crap, lobster, etc., John.e was fine to incorporate cod, salmon, tuna, etc., into his diet. We’ve been eating fish at least once a week since!

So, that’s the reason I’m able to finally make one of my favourite things to eat after a long day at work. Open Faced Tuna Melt Sandwiches are hearty enough to be a complete meal, but I always serve them with a few chips on the side.

You can easily adapt the sandwich to suit your personal tastes. You can leave out the onion, for example. Or skip the tomato. You can change up the cheese and use whatever cheese you prefer. Just make sure that the cheese is a good melting cheese. You really can’t go wrong, Dear Reader!

Now, have you tried any of my other seafood recipes? I have a weakness for tilapia – it’s one of my favourites – so you have to try my Sriracha Lemon Garlic Tilapia. And, in keeping with canned seafood, must like this recipe that uses canned tuna, canned salmon is also a great alternative. You’ve got to try my Salmon and Asparagus Pasta Salad too!

  1. Aw, I do sympathise and glad it's getting a bit easier for you to cook and to eat some of the things you like. I'm the cook, planner, shopper etc in our household, but as I'm vegetarian, it's not really an issue for me. Everyone gets to eat what I cook - so it's vegetarian all the way. Those sandwiches to look good and I know CT would love them.
