This lemon-Dijon vinaigrette is the only low FODMAP salad dressing you need. It's so much more flavorful than store bought brands and can be adapted to use any type of vinegar, like balsamic, or be sweetened with maple syrup. This version is sugar-free to be SIBO and gut-friendly.
In a medium mixing bowl whisk the mustard, lemon juice and salt together until combined.
Working slowly, add 1 teaspoon of oil in a thin drizzle and whisk or pulse until incorporated. Repeat with 3 additional teaspoons, one at a time. Once the oil is taking, slowly drizzle in the remaining olive oil, whisking or pulsing throughout.
Taste for seasoning and add more salt or oil as necessary. The best way to test it is by dipping whatever leaf of lettuce you’ll be eating into the dressing.
