When I was a kid, my mom always grew a large garden, and we ate out of it—beans, tomatoes, and corn were staples—all summer long. My sister and I each had our own patch, too. I won't lie though, mine was usually overtaken with weeds by the middle of summer!

Now that I live in the city, garden fresh tomatoes are a little harder to come by. They're definitely worth seeking out though, especially for this Tomato Avocado Sandwich!

Ingredients

This recipe uses simple ingredients you can find in any grocery store! Here's what you'll need:

Tomato - Choose the freshest tomatoes you can find for this recipe.
Avocado - Since store-bought avocados are usually pretty hard, plan to buy them a few days in advance (and let them ripen on your counter). And I always recommend purchasing an extra avocado or two, because you never know what you'll get once they're cut open!
Bread - I used whole wheat bread here, but almost anything works! This sandwich would be delicious on sourdough or another artisan-style bread, if you have it.
Sauce - The simple, but super delicious sauce is made with a combination of Greek yogurt, fresh basic, garlic, and sriracha sauce.

You'll Also Need:

To make the sandwich, you need to small bowl to prep the sauce, as well as a sharp knife to cut the tomatoes and avocados.

Variations

Ready to put your own stamp on this simple Avocado Tomato Sandwich? Here are some easy ideas to try:

Mashed Avocado - Use mashed avocado rather than sliced for a creamier texture. You could even substitute homemade Guacamole!
Herbs - Try adding different herbs to the yogurt spread, like chives, dill, thyme, rosemary, parsley, tarragon, or cilantro.
Sauces - Swap the yogurt dressing out for another sauce, such as Pesto, Romesco Sauce, or mayonnaise (or Pesto Mayo). Pickled Onions or Roasted Garlic would also be delish!
Toasted - Add some extra texture by toasted with bread before topping with the other ingredients.
Olives / Capers - Briny olives and capers are a great way to add a more complex flavor.
Vegan + Dairy Free - Replace the Greek yogurt with plain vegan yogurt to make this recipe vegan. Or use your favorite vegan spread or cheese (it would be delish with this Miyokos Garlic Herb Cheese!).
Gluten Free - To make the recipe GF, just substitute your favorite gluten free bread.
