To make salad, combine cooked amaranth, quinoa, diced tomatoes, cucumber, red onion, jalapeño and cilantro in a large bowl.
In a small bowl, whisk together minced garlic, apple cider vinegar, whole grain mustard, and honey. Then drizzle in extra virgin olive oil while whisking vigorously.
Dress salad with dressing, place in bowls and garnish with avocado.
