Tips For Making This Sandwich Recipe
If you plan on making this loaded veggie cheese sandwich, here are a few tips to make this recipe extra delicious:
- It may be a crime to make this recipe outside of peak tomato season. The freshness of the produce really makes this sandwich extra special, from the sweeter taste to the crisper feel, it’s the best way to enjoy this.
- To make mashing your avocados easier, score the fruit while it’s still in the skin, before scooping it into the bowl. It’s much easier to mash once it’s already in smaller pieces.
- If making this sandwich ahead of time, instead of putting the spreads directly on the bread, put the cheeses on the outsides of the sandwich fillings. The cheese will protect the slices of bread from getting too soggy!

Recipe Details
Mash the Avocado
To assemble this sandwich, it takes just a few steps of prep work before you’re digging in! To start, you’ll make a couple of spreads: a mashed avocado and an herby yogurt spread. The mashed avocado is a simple, but delicious mixture of avocado, lemon juice, and a pinch of sea salt. These ingredients will be mixed together to create a smooth, spreadable mixture.
Mix the Herby Sandwich Spread
The second step is an herby spread, which is comprised of greek yogurt, mayonnaise, and chopped, fresh herbs. I recommend using a variety of your favorite soft herbs, such as dill, basil, cilantro, parsley, and chives.
Before assembling your sandwich, get all of your ingredients prepared. Thinly slice your cucumber, tomato, and roasted red pepper. Clean and dry your baby spinach and grab your olive oil, salt, and pepper.
Build the Sandwich
To build the sandwich, layer the yogurt spread, cheeses, avocados, tomatoes, cucumber, spinach, and roasted red pepper. Drizzle a bit of olive oil and a sprinkle of salt and black pepper. Top your sandwich with a second slice of bread, slice each sandwich in half, and enjoy!
