Make the “Mayo”: In a large bowl, combine the vegan mayo, lemon juice, mustard, and poultry seasoning. Season with black pepper to taste. Whisk everything until it’s well-combined and creamy. The consistency should be smooth and spreadable. This homemade mayo is not only easy to make but also far superior to store-bought!
Mash the Chickpeas: Add the drained and rinsed chickpeas to the same bowl. Using a potato masher or a fork, mash the chickpeas to your liking. Personally, I prefer to leave about 25% whole for added texture. You want a mixture that's creamy yet still has some substance.
Add the Add-Ins: Toss in the thinly sliced celery, diced red onion, chopped parsley, almonds, and halved grapes. Mix everything together until well incorporated. Taste the mixture and adjust seasoning with additional salt and pepper if needed. You should have a vibrant, colorful mixture.
Serve Immediately: You can serve the chickpea salad immediately, or refrigerate it in a sealed container for up to 7 days. It’s a great make-ahead option that allows the flavors to meld over time.
Assemble Sandwiches: To put together each sandwich, start by lightly toasting your bread. Lay down a piece of lettuce on each slice, adding a generous portion of the chickpea salad on one side. Fold the other slice of bread on top to create your sandwich.
Serving Suggestions: These sandwiches can be enjoyed as is, but they’re also delicious served with a side of fresh veggies, crackers, or even on a bed of greens for a lighter meal. Get creative with your serving style!
