Cook the couscous according to package directions. In the meantime, prepare all of the vegetables.
In a high speed blender, combine dressing ingredients until smooth, apart from the parsley and black pepper. Stir that in at the end for a more textural ranch.
Add all of the salad ingredients to a bowl, and drizzle the dressing over top. Enjoy immediately or store in a sealed container in the fridge for up to 4 days.
Notes
Swap the navy beans for chickpeas, edamame, butter beans, or even fresh peas. Use whatever you have in your pantry or freezer!
If you want a couscous substitute, use quinoa, farro, or orzo. Quinoa works well if you're looking for a gluten-free option.
Don't toss out the radish tops! They add a peppery flavor similar to arugula.
For a nut-free vegan ranch dressing, use hummus or tofu as the base.
Turn this into a mason jar salad for easy grab-and-go lunches.
This recipe yields 4-6 servings depending whether you serve it as a main or side.
