Have you ever written a list of your favorite foods?

Avocado is at the top of my list. Yes of course there are other favorites—artichokes, blueberries, a good steak—but avocado is queen of them all.

As long as I can remember, my family has always had avocados in the house, either out on the counter ripening, or in the fridge. For a couple glorious years we even had an avocado tree, until it died in a freeze. :-(

So no wonder my father’s most treasured sandwich is, as he affectionately calls it, the A.L.T.—avocado, lettuce, and tomato, on toast.

Avocado Lettuce Tomato Sandwich

Of course he thinks he invented this sandwich, and he did, as have thousands of other avocado lovers around the world. I once asked him, why not add bacon?

His response? A grumbled, “Why should I? It’s perfectly fine with avocado,” along with a look that said, if I wanted a BLT I would have made a BLT.

That’s my dad. Do not get between him and his food.

Of course if you want to add a couple strips of bacon to your ALT (that would make it a BLAT), be my guest!

Avocado Lettuce Tomato Sandwich (ALT) Recipe

  • Prep time: 10 minutes

The key to a delicious A.L.T. is salt. The flavor of both avocados and tomatoes shines with the addition of a little sprinkling of salt.


  • Toasted whole grain bread
  • Sliced avocado (see How to Cut and Peel an Avocado)
  • Lettuce (Boston Bibb or butter lettuce work well)
  • Sliced fresh tomato
  • Kosher salt
  • Mayonnaise


1 For each sandwich, toast two slices of whole grain bread. While the bread is toasting, slice your tomato and avocado.

2 Slather as much (or little) mayonnaise as you like on one side of each slice of toasted bread. Add a layer of sliced avocado and sprinkle a little kosher salt over it. Add a layer of lettuce and a layer of sliced tomatoes. Sprinkle a little salt over the tomatoes too.

3 Top with the second slice of toasted bread. Cut the sandwich in half if you want, to make it easier to eat.  Enjoy!

    I love making this… I use brownberry Heath nut bread, I toast it in the oven and put a slice of deli American cheese on it. I also add sliced red onion and it’s amazing!!

  2. Kevin

    Add a thin layer of Marmite (or Vegemite) if you dare.

    Great recipe I love avocado! I like to put Italian dressing on my sandwich.

    I would not or never include bacon in this, I would use a “French bread”, and add some thinly sliced ham, some boiled eggs, some cheese, and a little mayonnaise, with the lettuce and tomatoes, with some salade sprouts…that’s how we do this in Belgium! Bon Appetit!

    When my husband and I lived in the Philippines (eons ago), our cook prepared my now favorite variation to add to the ALT. She butterflied a huge prawn, breaded it and sautéed it (with a small strip of lemon zest in the oil to add some freshness and flavor) to take center stage in the ALT sandwich. One large prawn butterflied was big enough to cover an entire slice of bread. I thought I’d died an gone to heaven…and I’m not a seafood lover! I still make it as a dinner sandwich occasionally. Buying only one or two huge prawns to make a couple of sandwiches isn’t so expensive as to make it an unreasonable purchase for a casual dinner.
