Is this Keto tuna sandwich healthy?

Whether this Keto sandwich is healthy or not depends on the ingredients. The eggplant “bread” is low in carbohydrates, full of nutrients and fiber, and easily accessible. It definitely beats any other Keto bread. As for the tuna filling, prepare it using sustainably caught canned light tuna, which is lower in mercury, and use organic mayo. You can add avocado and greens to the sandwich to boost the nutritious value.

How to make the eggplant “bread” slices?

The most important aspect when preparing this eggplant “bread” is the type and size of the eggplant you use. Choose a globe eggplant with a girth of 5-6 inches (11-13 cm). Cut 4 round slices from the center, each with a thickness of ½ inch (1 cm). Brush the eggplant slices with olive oil and cook on a griddle pan until just cooked. You need it to be a bit firm to hold the filling. To avoid sogging, fill the sandwich right before serving.

How can you customize this Keto sandwich?

This tuna sandwich is meant to be prepared with simple flavors already in your kitchen. So if you have a missing ingredient, you can swap it for another from your pantry. Instead of mayonnaise, you can use sour cream, Caesar dressing, or ranch dressing. You can replace the parsley with dill or chives and the onion with grated carrots, chopped pickles, or celery. If you’re not in the mood for tuna, you can replace it with canned salmon, shredded cooked chicken, or leftover boiled eggs.
