I grew up on a lot of Weight Watchers and "light" recipes because my Mom cooked healthy food and followed the WW program herself for many years. Honestly, it was just normal healthy eating to me and I never thought much of it. This Tomato Stuffed with Tuna recipe is great any time of the year, but especially when fresh tomatoes are in season! They make a great quick lunch for home or work or a healthy dinner.

🍅 Tuna Stuffed Tomatoes Recipe

Sometimes my kids complain about eating Weight Watchers recipes, but they also love many of them. And they don't even realize they are eating a WW recipe half the time anyway.

And of course, I don't tell them until AFTER they tell me how much they love it. I've lightened up a few of my regular recipes to make them WW friendly and my kids actually like my WW Butter Chicken , WW Creamy Lemon Pasta, and WW Blueberry Cornbread better than the original! Seriously, these recipes are so good you'd never even know they are Weight Watchers friendly.

🥘 Ingredient Notes

These tomatoes stuffed with tuna only need a few ingredients:

Fresh tomatoes. I use whatever tomatoes I have on hand, such as Hothouse tomatoes but any fresh, ripe tomatoes will work. A round tomato, such as a sandwich tomato is easier to stuff than an oblong tomato like Roma.
Canned tuna. I recommend a flaked tuna in water. It's easier to work with than chunk tuna and the water keeps it low-calorie.
Mayonnaise. I use Hellman's ½ the fat mayonnaise. It's lower fat (and points and still tastes delicious!

*Please see recipe card for full list of ingredients and quantities

📖Variations & Substitutions

Dairy-free- use a dairy-free plant-based mayonnaise alternative
Tuna - use flavored tuna or canned salmon instead of tuna.
Spicy - add a dash of hot sauce or sriracha to the tuna mixture. Mix in some diced jalapeños or chili flakes.

Expert Tips

Choose the Right Tomatoes. Use firm, ripe tomatoes that are large enough to hold the filling but not overripe, as they can become too soft and fall apart. Round tomatoes like beefsteak or hothouse varieties work best.
Prevent the tomatoes from getting soggy. Scoop out the tomato pulp carefully, leaving a thicker shell (about ¼ inch). Pat the inside of the tomatoes dry with a paper towel before stuffing. Serve them immediately after preparing, or store them briefly in the refrigerator.
Drain the Tuna Well. Make sure to thoroughly drain the canned tuna before mixing it with the other ingredients. Excess liquid can make the filling too wet and may cause the tomato shells to break down faster.
Packing Tuna Stuffed Tomatoes in a lunchbox. Use sturdy, firm tomatoes to ensure they hold their shape. Place the stuffed tomatoes in a compartmentalized container to keep them upright. Include a cold pack to keep them fresh.
Chill Before Serving. These stuffed tomatoes taste even better when chilled for 20-30 minutes. It allows the flavors in the filling to meld together.
