Make this easy low-carb tuna recipe for breakfast or lunch! It’s high-protein and good source of antioxidants. To meal prep this tuna omelette recipe: pour the mixture into muffin cups, bake and make mini frittatas to grab and go.
After 2-3 weeks of eating “vegan”, last week I decided to load on some protein and on vitamin D to help me get out of the slump I was in. It was rainy and dark all the time, so chickpeas somehow weren’t enough. But I do still love you, dear chickpeas.
So, I was craving fish like never before. But I didn’t want my house to smell like fish – I opened a can of tuna (go ahead and judge me – I don’t care) and came up with this high protein and low-carb
It’s like a tuna frittata, but I called it an omelette originally, because I didn’t realize it’s a frittata.
Then I made all kinds things with this recipe. I discovered you can also bake this mixture in muffin cups in the oven. I haven’t done it with tuna, but I’ve tried with broccoli and other vegetables and it’s just delicious.
It’s a healthy high-protein snack that’s perfect on the go. Take 2-3 and you’ve got a lunch.
Health Benefits
These tuna frittatas (let’s call them that) are rich in antioxidants, protein, low in carbs. Plus they are a good source of vitamin D, which is awesome, if you, much like me, live where the sun doesn’t shine – the ass of the universe.
Ok, poetry class dismissed. Now let’s do this.

OMG!!! This is like the one of the best protein meals ever! I have a full cupboard of tuna and was thinking where to use it for a while now… thank you so much?????
Thank you, Brigita, haha sounds like you found the perfect recipe for all that tuna! If you get sick of making this in a pan, you can also bake the mixture in muffin cups – it’s like mini frittatas – pretty sure it will work, you might need some olive oil in the mixture though.
