Crafting your Chickpea Salad Sandwich is as easy as following these simple steps:

1. Prepare Chickpeas: In a medium bowl, mash the drained and rinsed chickpeas with a fork or potato masher until mostly smooth, leaving some chunks for texture.

2. Combine Ingredients: Add the mayonnaise, Dijon mustard, grated carrot, diced celery, chopped red onion, garlic powder, and lemon juice to the bowl. Mix everything until well combined.

3. Season: Taste the mixture and add salt and pepper as needed. If using, fold in the chopped fresh herbs for additional flavor.

4. Chill (Optional): For enhanced flavors, cover the bowl with plastic wrap and refrigerate the chickpea salad for 30 minutes to 1 hour.

5. Prepare Bread: While the salad chills, toast your bread slices lightly for added flavor and crunch.

6. Assemble Sandwich: Spread an ample amount of the chickpea salad on one slice of toasted bread. Top it with another slice to create a sandwich.

7. Serve: Cut the sandwich in half for easier eating and serve with your favorite sides.
