Tips & Tricks

Serving tips

This recipe yields only two servings, but you can double or triple the ingredients if you plan to make it for a whole crowd. But whatever you do, make sure to serve this salad fresh since avocados tend to brown soon after opening. Lemon juice helps slow down oxidation in avocados, but it definitely doesn’t stop it.

Health benefits

Avocados are rich in monounsaturated fatty acids (MUFAs), which are protective against cardiovascular disease. Tuna is rich in a type of omega-3 fatty acid called DHA, which also keeps your blood vessels healthy but also your brain. Together these ingredients make for a powerful combo. Another plus is the 6g of fiber in a serving along with vitamin E, folate, and potassium.
