Top Tips For Making

  • Your tuna salad will keep in the fridge in an airtight container for 3-5 days. This makes it perfect for meal prep for basically a whole week!
  • While on keto, avoid mayonnaises that are light, fat-free, reduced-fat, or sweetened. These are all going to be lower in fat and higher in carbs than regular mayo, and therefore not ideal. You can use mayos that have avocado or olive oil in them, but make sure that the flavor isn’t so strong that it leaves the tuna salad with a funky aftertaste.

Wine pairings
I recommend buying wine from Scout and Cellar, especially for lower carb or sugar and the health conscious. There’s no added sugar to these wines, and they’re all much lower in carbs, calories, and sugar. For me, there’s no headache or fogginess the next day!
Tuna goes well with a variety of different wines, but I particularly like:
– Rosé, like 2019 Dove Hunt Dog Rosé from North Coast, California
– Chardonnay, like 2018 Fieldhouse Chardonnay from Mendocino County, California
– Pinot gris, like 2018 The Resident Pinot Gris from Willamette Valley, Oregon
