Tuna sandwiches are so easy to make. Especially for busy families – which is like every family out there! Though I love plain tuna sandwiches, the added avocado with a boiled egg and tomato take this open-faced to a whole new level.

Skipping on the second slice of bread saves so many calories and the taste is still as wonderful.

Avocado and egg is a great combination. However, it’s a typical combination to enjoy for breakfast and is by far my favorite breakfast combination. When you take avocado and egg then add it to a creamy tuna mixture with a crispy garlic French bread – it’s love at first bite.

how to make tuna sandwich-

  • Toast French bread and rub a garlic clove over the warm slices.
  • Prepare tuna mixture.
  • Slice the avocado, tomatoes and boiled eggs.
  • Add tuna to cooled bread slices and top with avocado, tomato and egg.

TIP: I love garlic so I add minced garlic to the tuna mixture as well as rubbing garlic over the bread slices. If you aren’t too big of a garlic fan, do one or the other.

Note: I love the crunch and flavor onion adds to the tuna. If you don’t like the onion, you can leave it out.
