Tuna and Chickpea Mason Jar Salads

Step 1: Make the Lemon-Herb Dressing

In a small bowl or jar, combine the olive oil, fresh lemon juice, minced garlic, Dijon mustard, dried oregano, honey, salt, and black pepper.

Whisk everything together vigorously until the dressing is fully emulsified — it should look thick, glossy, and slightly creamy rather than separated.

Taste and adjust: if it needs more brightness, add a squeeze more lemon; if it's too sharp, add a tiny drizzle more honey. Set aside.

Step 2: Prep All Your Vegetables

Halve the cherry tomatoes, dice the cucumber into roughly 1/2-inch pieces, halve the Kalamata olives, finely dice the red onion, and slice the roasted red peppers into thin strips.

Give the rinsed chickpeas a pat dry with a paper towel — this helps them absorb the dressing better and keeps them from making the jar watery.

Chop the fresh parsley and have your baby spinach or mixed greens ready. Keeping everything prepped and organized makes assembly quick and stress-free.

Step 3: Add the Dressing to the Bottom of Each Jar

Divide the lemon-herb dressing evenly between four wide-mouth quart-sized mason jars — about 2 tablespoons per jar.

Pour the dressing in first — this is the most important rule of mason jar salads. The dressing sits at the very bottom, away from the greens, so nothing wilts before you're ready to eat.

Tilt the jar slightly if needed to make sure the dressing coats the bottom evenly.

Step 4: Layer the Hearty Ingredients First

On top of the dressing, add the chickpeas — they are sturdy enough to sit right in the dressing without getting soggy, and they'll actually absorb all that lemony flavor overnight.

Next, add the cherry tomatoes and then the diced cucumber in an even layer.

These dense, water-resistant ingredients form a protective barrier between the dressing and the more delicate components that come next.

Step 5: Add the Tuna, Olives, and Peppers

Drain the canned tuna thoroughly and break it into large, chunky flakes with a fork — you want texture, not mush. Divide it evenly between the four jars.

Add the Kalamata olives, roasted red peppers, and finely diced red onion on top of the tuna layer.

This middle section is where all the big Mediterranean flavors live — briny, sweet, savory, and a little punchy from the onion.

Step 6: Top with Greens and Parsley

Pack the baby spinach or mixed greens tightly on top — don't be shy, greens compress a lot and you want a full, satisfying salad when you shake it out.

Scatter the chopped fresh parsley over the greens as the final layer.

The greens must always be the very last thing you add. Their position at the top, furthest from the dressing, is exactly what keeps them crisp and fresh for up to four days in the fridge.

Step 7: Seal, Store, and Serve

Screw the lids on tightly and store the jars upright in the refrigerator for up to 4 days.

When you're ready to eat, shake the jar vigorously with the lid on to distribute the dressing, then either eat straight from the jar or pour into a wide bowl for easier tossing.

The salad will taste even better on day two and three as the chickpeas and tuna soak up all that garlic-lemon dressing — trust the process.
