In a mixing bowl, add the drained and rinsed chickpeas. Use a fork to mash them gently, leaving some whole for texture.

Add the finely diced celery, red onion, red bell pepper, and chopped parsley to the bowl. These ingredients add crunch and flavor.

In a separate small bowl, whisk together the lemon juice, olive oil, Dijon mustard, garlic powder, salt, and black pepper until well combined. This dressing will enhance the flavors of the salad.

Pour the dressing over the chickpea mixture and stir until everything is evenly coated. Taste and adjust seasoning if necessary.

Lay out the slices of whole grain bread on a clean surface. This will be the base for your sandwiches.

On four slices of bread, layer a leaf of romaine lettuce, followed by a generous scoop of the chickpea salad.

Top with slices of tomato for added freshness and flavor.

Finish with the remaining slices of bread to create sandwiches. Press down gently to hold everything together.

Cut each sandwich in half diagonally for easy serving and enjoy!
