You can make the filling for this white bean veggie sandwich a day or two ahead and pop it into the refrigerator. The white bean filling also makes a nice dip for veggies or chips. These sandwiches are great for taking along on picnics or outings.
One thing I recommend is to use a good quality 100% whole grain or multigrain bread. Whole grain bread is healthier and because the slices are dense, the sandwich holds up better and is easier to cut. I think red onions are best for adding spice to this sandwich, with their strong flavor, but any type onion will do. You can add arugula or sprouts (or both) to these sandwiches for crunchiness and chewiness. For the cucumber, I prefer English cucumber, which I’ve said in the suggestions for lot of recipes. It has a stronger cucumber aroma and flavor and is consistently delicious. I’ve never bought a bland or overly watery English cucumber.
Once you’ve sliced the avocados, squeeze lemon juice over them on a dish and gently toss them until they are coated. This will keep the avocado from turning brown, but it also, obviously, adds that fresh citrus flavor. I like to sprinkle the avocados with black pepper, too, before adding them to the sandwich.
Just before putting the two sandwich halves together, I add another shake of salt and pepper for a yummy deli flavor. You can also use Everything Bagel seasoning instead of salt and pepper, which adds a stronger garlic and onion layer of flavor. I make my own homemade Everything Bagel Seasoning – it’s quick and easy and so great to have on hand.
To prevent sogginess, especially if you aren’t going to eat the sandwiches right away, place the lettuce and arugula or sprouts right next to the bread, so that no wet ingredients touch the bread. It’s an easy way to keep the bread dry and mushy-free.
I use romaine lettuce but any leafy lettuce will work. If you like more crunch, use iceberg. If you want something super green, use a softer leaf lettuce or even spinach. Play around with all the ingredients and make this yours!
This recipe makes four full sandwiches using the large bread slices. If you need more than four sandwiches, consider serving half sandwiches with soup or another side. The recipe can easily be doubled, too.
