Healthy Tuna Salad Sandwich

Healthy Tuna Salad Sandwich – Freezer Meal Ideas for Lunch!

Take tuna salad to the next level in a tasty GRILLED sandwich! To lighten things up, I’ve used hummus for creaminess instead of the traditional mayonnaise. And, this healthy tuna salad sandwich recipe is perfect for meal prep, because you can actually FREEZE it!

For my tuna melt, I used a Panini press to get those lovely grill marks. But, you can also heat it in the toaster oven or on the stove—or just eat it cold! Seriously, this healthy tuna salad sandwich is so scrumptious, I like it BETTER than the classic recipe. And, the tuna salad itself is also delicious all on its own! A great no cook meal prep lunch idea or on-the-go work lunch.

Dairy Free, Low Fat Tuna Salad

A healthy tuna salad sandwich seems unexpected when you consider the main ingredients for tuna salad: tuna and mayonnaise. And, while mayo can totally be health-ified, it’s still high in fat. Granted, fat is fuel and dietary fat is important. But, if you’re not on a high fat or keto diet, you likely want to limit your intake.

Ultimately, a balance of macros is what’s important, and eating bread means eating carbohydrates. Long story short, if you’re eating a diet high in carbs, you’ve got to watch fat intake. Similarly, if you’re eating a diet high in fat, you’ve got to watch your carb intake. One isn’t better than the other (necessarily)—what’s more important is what’s right for YOU.

So, since this post is all about healthy sandwich ideas, we’re keeping the carbs, and cutting the fat. (For now…)

Meal Prep Sandwiches – Healthy Sandwich Ideas! 

Sandwiches can be tough to meal prep, but some work better than others. First of all, mayonnaise isn’t a condiment that survives a long time in a sandwich or freezer. But, hummus on the other hand can totally freeze! Freezer sandwiches—why not!?

In this healthy tuna salad sandwich, the hummus provides creaminess like mayo and keeps the recipe dairy free. And, adding other ingredients like relish and onion give an extra boost of flavor! Once prepped, you can store your healthy tuna salad sandwich in a plastic bag and refrigerate or freeze.

Then, when ready to eat, I like to press mine in a Panini press, or waffle maker! It makes it taste like a freshly-cooked meal with very little extra effort! But, if you do freeze your healthy tuna salad sandwich, be sure to thaw it out in the fridge the day before you want to enjoy.

Making this Healthy Tuna Salad Sandwich Low Carb

Now, what if you want a lower carb option? The simplest route is to simply enjoy this tuna salad on its own or on a bed of greens. But, you could also serve up a healthy tuna salad sandwich in a lettuce or coconut wrap!

Really, the carbs here are all from the bread, which is totally optional. Of course, making this healthy tuna salad sandwich low carb means you won’t be roasting it. But, it will still be a totally delicious and convenient meal prep lunch idea!
