But, before jumping straight to this scrumptious low carb tuna melt recipe, I want to discuss a few things about the ingredients.
Tomatoes On Keto Tuna Melt Sandwiches
Tomatoes are considered as fruits according to the botanical classification and as fruits generally contain high carbs per serving (20-25gms).
Many people tend to think that tomatoes too are not keto-friendly.
However, unlike other fruits tomatoes contain only 2-3 grams of net carbs per 100 grams serving (3.5 ounces), which is up to 10 times lower than most other fruits.
Note that these values may change according to the type of tomatoes you choose. For instance, cherry tomatoes have around 6 grams of carbs in their content.
Also, make sure that you use whole tomatoes because store-bought tomato products such as tomato juice, canned tomatoes, sauce, and salsa are often packed with sugar.
Additionally, tomatoes are a great source of dietary fibers along with vitamin C, B9, K, folate, and minerals like potassium.
Plus, it also contains a powerful antioxidant called Lycopene.
Various studies suggest that supplementing Lycopene helps to lower the harmful LDL cholesterol levels and thus protects us from various heart diseases.
Pro-tip – the highest concentrations of Lycopene are found in the skin so, the redder the tomato, the more Lycopene it has.
As we all know that tuna is saltwater fish and contains NO or less than 1 gram of carbs per ounce of serving.
Moreover, they are fairly high in protein content an ounce of it can provide almost 5 grams of protein, which is especially great for this keto tuna melt recipe.
All of these make tuna an ideal food for the standard
In addition, consuming tuna has many benefits. Some of them are,
- Tuna is loaded with omega-3 fatty acids, which are considered heart- healthy because they tend to decrease the risk of strokes and heart failure.
- It contains a high level of selenium, zinc, and protein which are essential to maintain proper immune system functions.
- Consuming Tuna provides vitamin D which helps in the absorption of calcium and phosphorus thus, it strengthens your bones.
- Tuna is a high protein, low carb, and low-fat food that is ideal for individuals who are trying to lose weight.
Besides these, I have also used celery, red onions, parsley, and lemon juice which not only uplift the overall flavors of the dish, but also provide many health benefits as they are filled with antioxidants.
Moreover, note that I have used low carb bread to keep this open faced tuna melt recipe keto-friendly.
Further, I love how customizable this keto tuna melt recipe is, for instance,
- If you want to up-level on your keto diet you can totally skip the low carb bread and use tomato slices as the base.
- If you like to change things up, you can replace celery with other crunchy vegetables of your choice.
- You can alter the amount of cheese and mayo according to your daily caloric requirements.
Low Carb Bread Options
For this recipe to keep it low carb be sure to use a bread that is sturdy, yet lower in carbohydrates.
I recently tried Franz Keto sandwich bread. This is probably one of the most wheat-like sliced white bread and the convenience can’t be beat.
Half of a slice is the perfect amount for an open faced sandwich. You can purchase this bread online or at Costco.
However, before experimenting, I would really suggest you to try this perfected version of the keto tuna melt recipe.
