I love the taste of the tomato with the tuna and the cheese so much better than if there was bread. 


What Are The Best Tomatoes To Use

Reach for a medium to large style tomato. Hothouse or beefsteak tomatoes are great. 


Make sure the tomatoes feel and look good. Look for wrinkles on the skin, being extra soft, or any other markers. 


How To Make

Step 1: Start by preheating your oven, and prepping your tomatoes. Use a spoon to scoop out the filling in tomatoes.

Step 2: In a bowl work on your tuna salad portion. Once your mixture is ready, spoon into tomatoes. Full all the tomatoes to the top. Top them off with cheese.

Step 3: Toss tomatoes in the oven and bake. All ovens cook differently so pull out when the cheese is starting to turn golden brown.

Can I Double This Recipe 

Tuna stuffed tomatoes are truly a treat. Especially if you havescome from a garden or farmers market. 


So go ahead and make more if you need. Just batch cook if you need. 


Do Stuffed Tomatoes Store Well

Stuffed tomatoes are best when served fresh from the oven. You will find that tomatoes will become extra soggy if refrigerated. 


They can be stored in the fridge but just know the texture will change. 


Could I Swap Out Tuna With Chicken

Not a big fan of tuna? Feel free to mix up some shredded chicken. You will want to ensure you cook the chicken first and then shred or dice. 


Sometimes I do a mix of both so my family has a choice on what they want. 


So don’t wait and try this easy keto tuna recipe a try.  It is affordable, easy, and essential ingredients are needed.
