Roasted Chickpeas as Healthy “Croutons”

One of my favorite ingredients for this recipe is the chickpeas! They don’t go inside the soup, but rather roasted and served as a healthy version of “croutons” on top of your soup!

When you roast chickpeas, they have such a lovely, nutty flavor and add such a great texture to this soup!

Don’t skip this step as you’ll likely be missing out on the best part of this yummy soup!

Roasted Tomato & Barley Soup for the 17 Day Kickstart Diet

You might be aware that Dr. Mike created a brand new, plant forward diet called the 17 Day Kickstart Diet. It’s based on the original 17 Day Diet and is focused on getting more greens and fish and plant based proteins in (it’s definitely not a vegetarian diet as chicken, beef, pork and shellfish are also allowed).

This Roasted Tomato & Barley Soup is definitely plant-forward and it’s ideal for the 10-Day Stabilize Phase of the Kickstart Diet when grains such as barley is introduced.

If you wish to use this recipe in an earlier phase such as the Scrub or Soak Up Phases, then you’d need to omit the barley. 

If you’re not sure of the approved foods for each phase, make sure you take a peek at the 17 Day Kickstart Diet Food List.

Roasted Tomato & Barley Soup for the 17 Day Diet

If you’re on the 17 Day Diet, then you too can enjoy this lovely soup!

This recipe is approved for Cycles 2 and 3 of the 17 Day Diet and would make the perfect lunch as natural starches should be eaten by 2pm on the 17 Day Diet.

Also, make sure you use approved sweetener (i.e. stevia or monk fruit) or you can omit it all together depending on how sweet the tomatoes roast up!

Grain Substitutions

If you don’t have any barley on hand, no worries! Here are a few substitutions you may use:

During the Stabilize Phase of the Kickstart Diet, consider using:

  • Quinoa (this won’t be as “hearty”, but it will still work and provides extra protein)
  • Bulgur
  • Brown Rice
  • Farro

If you’re on the 17 Day Diet, you may use the following:

  • Amaranth
  • Brown Rice
  • Long grain rice (such as Basmati)
  • Millet
  • Quinoa

The starches listed above may be used during Cycles 2 and 3 of the 17 Day Diet.

There are many grains you may use instead of barley in this roasted tomato soup

Protein Boosts To Add To Soup

If you want to add a bit of plant-based protein to your soup, consider adding the following:

  • Lentils
  • White Beans
  • Quinoa
  • Soy Beans

The sky is the limit when it comes to adding in extra protein into this lovely soup, so make it your own!

Roasted Tomato & Barley Soup for the soul


  • 4 lbs. small tomatoes (plum or roma)
  • 3/4 cup uncooked barley
  • 2 cups vegetable stock

  • 1 tbsp. avocado oil
  • 4 cloves garlic, crushed
  • 2 tsp. fresh thyme

Spicy Chickpea Croutons:

  • 14 oz. canned chickpeas
  • 10 drops sriracha sauce or a few sprinkles of sriracha seasoning


  1. Preheat the oven to 350°F.
  2. Cut the tomatoes in half or quarters and place on a baking sheet. Sprinkle the tomatoes with salt and pepper and a drizzle of olive oil and bake in the oven for 35 minutes until soft.
