Ingredient-Stretching Tip: Use any extra avocados to make this blue cheese salad or salad with smoked turkey.
Sardines aren’t the most popular fish around, but what is popular are chickpea and avocado salad sandwiches. With that said, I think sardines deserve a little more love in this world, and incorporating them into smashed chickpeas and avocado is one way to do it.
And that’s what we’re doing here with this smashed chickpea salad sandwich with sardines.
If you’ve never had sardines, they taste similar to tuna but are a bit more pungent. That’s why this sandwich mixes them into other key ingredients, so they don’t overwhelm the palate but still offer that tuna-like quality (assuming you’re into tuna and up for something different).
Sardines are also packed with nutrients like omega-3 fatty acids, so this sandwich is a great way to enjoy a healthy and tasty lunch. It’s also easily customizable: Top with sliced tomato or different lettuce greens, add diced celery or sliced scallions, etc., to tweak this sandwich to your liking.

How to Make This Smashed Chickpea Salad Sandwich with Sardines

Recipe FAQs
Sardines taste similar to tuna, but are a little more pungent. If you like tuna, it’s probably safe to say you’ll like sardines. However, if you’re new to this tasty, nutrient-dense fish, taste a piece from the can first. If you find it too strong, simply use less than the entire can for this recipe. You can also compensate by adding more chickpeas and avocado; just note that you may need to adjust the amount of supporting ingredients (add more salt, mayo, etc.).
You can make the salad ahead of time, but I would hold off on assembling the sandwich until you’re ready to serve it. Also, leave out the avocado from the salad until you’re ready to serve it because it may turn brown. Cover the partially made salad and store it in the refrigerator until ready to use.
Storage
Refrigerator: Store the leftover sardine salad in an airtight container in the refrigerator for up to 2 days.
