As a Spread

Mashed avocado or guacamole is great spread on whole grain bread, dipped with crackers, or topped on tacos. But if you go a bit further, avocado can also make a really tasty mayonnaise substitute. The principle is the same as avocado dressing, except you don’t thin the mayo as much as you would the dressing.
Ideal seasonings include garlic powder, onion powder, and salt and pepper. Use white or cider vinegar and lemon juice for the acid component.
