Gluten Free Tuna Melt Tostados – Easy & Yummy!

Do you ever put certain foods together that other people would cringe at? I used to have all kind of interesting combos when I was a kid: my Grandmas meat loaf, mashed potatoes, gravy & peas all mixed up and chili and mashed potatoes topped with cheese are just a couple that stand out in my head. My sister still eats one of her childhood favorite combinations – Doritos and applesauce. I don’t think I have ever tried that, or not that I recall. I may have blocked it out. LOL! Anyway, I don’t judge, as to each his own.

The other day I was craving a tuna melt. I meandered into the kitchen and started to pull out the ingredients to create my meal and realized I had no base for the melt. I had run out of my Food for Life English Muffins and Trader Joe’s French Rolls. Clearly I was slacking in the gluten-free grocery department or eating too many carbs – maybe a little of both. I began to brainstorm about what I could use for the base. Did I want to bake? Not really. I just wanted to eat. I spotted my corn tortillas in the refrigerator and a light bulb went on – tuna melt tostadas! This turned out so good that I may be using this as a new standby in my lunch line up!


This turned out even better than I thought it would! I would absolutely make this again in a heartbeat!

Tuna Melt Tostadas

2 corn tortillas (most are gluten-free, but please double check the label to make sure)

Cooking spray

1 single serving pouch of tuna (I used the 2.5 ounce Bumble Bee)

1-2 tsp Hellman’s Canola Mayo (says “gluten-free” on the jar)

1 tsp sweet pickle relish (I used Meijer – says “GF” on the jar)

1 squirt French’s Spicy Mustard (Trader Joe’s is good, too)

Cheddar cheese


1. Preheat oven to 375 – 400 degrees.

2. Combine tuna, mayo, relish and mustard. Set aside.

3. Place corn tortillas on a baking sheet that has been sprayed with cooking spray. Spray tops of corn tortillas with cooking spray.

4. Bake tortillas until they start to brown & get crisp.

5. Top tortillas with tuna mixture and cheddar cheese. Broil until warm & melty.

6. Enjoy!

You can mix things up and add other ingredients to your tuna mix – celery, Sriracha, Red Hot, etc. Be creative!


What is the weirdest food combination you have ever tried? Do you have one that you eat on a regular basis?
