This versatile citrus salad dressing gets a touch of natural sweetness from orange juice, which balances the acidity of the lemon juice. Use it in coleslaw for a mayo-free dressing, or drizzle it over winter greens with dried fruit and nuts.
Combine shallot, orange zest, orange juice, lemon juice, mustard, salt and pepper in a blender or mini food processor. (Alternatively, combine in a jar and use an immersion blender.) Add olive oil and canola (or avocado) oil; blend until smooth.
To make ahead: Refrigerate dressing for up to 5 days.
