Add broth and quinoa to a pot fitted with a lid and bring to a boil. Reduce to a simmer and cook quinoa for 15 minutes (or until liquid has been absorbed), Let cool for 5 minutes
While quinoa is cooking, make the vinaigrette by adding the lemon juice and zest, white wine vinegar, and minced garlic to a medium-sized bowl. Slowly whisk in the oil and season with salt and pepper.
In a large salad bowl, add quinoa, garbanzo beans, bell peppers, onion and cilantro and mix to combine
Crumble in feta cheese and add dressing.
Notes
To get a nice emulsified dressing you may also choose to use an immersion blender
Although not necessary, you may choose to rinse your quinoa prior to cooking as it contains saponin, a naturally occurring chemical that can inhibit the nuttiness of the quinoa.
