This plant-based harissa chickpea smash sandwich has become my go-to lunch option for busy weekdays when I need something quick but refuse to compromise on flavor or nutrition. The creamy, spicy chickpea mixture paired with crisp vegetables creates a perfect balance that satisfies even the most discerning palates.
I first made this sandwich during a particularly hectic work week when I needed something that could be prepared ahead of time. Now it's become a regular in our lunch rotation, with my partner frequently requesting it for picnics and road trips.
Ingredients
- Chickpeas: provide plant based protein and create the hearty base
- Fresh lime juice: adds brightness and helps cut through the creaminess
- Harissa paste: delivers complex North African flavors with adjustable heat
- Celery: brings essential crunch and freshness
- Dried dill: offers subtle herbal notes that complement the spice
- Mayonnaise: binds everything together while adding creaminess
- Crusty bread: stands up to the filling without getting soggy
- Lettuce: provides a fresh crunch and visual appeal
- Radishes: add peppery bite and beautiful color contrast
- Optional honey drizzle: balances the spice with subtle sweetness
Step-by-Step Instructions
- Prepare the chickpeas:
- Thoroughly drain and rinse the chickpeas to remove any canning liquid. This prevents a tinny flavor and improves the texture. The chickpeas should be as dry as possible before mashing for the best consistency.
- Create the base mixture:
- Combine chickpeas, lime juice, harissa paste, dried dill, mayonnaise, salt and pepper in a medium bowl. Use the back of a fork to mash everything together. Leave some chunks for texture while ensuring enough is mashed to create a spreadable consistency. Start with less harissa and add more to taste depending on your heat preference.
- Add texture elements:
- Fold in the finely diced celery. The small pieces distribute evenly throughout the mixture while providing delightful crunch in every bite. The mixture can be refrigerated at this point, which actually improves the flavor as ingredients meld together.
- Toast the bread:
- Select a sturdy, crusty bread that can support the substantial filling. Toast until golden brown and slightly crisp on the outside while maintaining some softness inside. This critical step prevents sogginess once assembled.
- Assemble strategically:
- Spread butter or mayo on one slice of bread to create a moisture barrier. If using honey, drizzle it on the other slice. Layer lettuce first as another moisture barrier, followed by the chickpea mixture, then thinly sliced radishes. Top with the second slice of bread and serve immediately for best texture.

The harissa paste is truly the star ingredient in this recipe. I discovered it years ago during a cooking class featuring North African cuisine, and it transformed my plant based cooking. The complex blend of chili peppers, garlic, olive oil and aromatic spices adds incredible depth to even the simplest ingredients.
Storage Tips
The chickpea mixture stays fresh in an airtight container in the refrigerator for up to 4 days. The flavors actually improve after 24 hours as they fully develop and meld together. For meal prep, store the components separately and assemble sandwiches just before eating to maintain optimal texture. The bread should be toasted fresh for each sandwich.
Customization Options
This versatile recipe welcomes many adaptations. Swap the harissa for pesto, curry paste, or chipotle in adobo for different flavor profiles. Add diced red onion, bell pepper, or grated carrot for extra vegetables. Replace the mayo with Greek yogurt or avocado for a different creamy element. Serve open faced on thick toast for a lighter option, or wrap in lettuce leaves for a gluten free alternative.
Serving Suggestions
Complete your meal with a light side like a simple green salad, crisp vegetable sticks, or a cup of tomato soup. For entertaining, cut sandwiches into quarters and serve as an appetizer alongside other Mediterranean inspired dishes. This filling also works wonderfully as a dip with pita chips and crudités, or as a protein packed addition to grain bowls.
