Prep Time 5 mins
Cook Time 45 mins
Total Time 50 mins


  • 2 large red bell peppers
  • 1 cup sliced leeks
  • 2 cloves garlic
  • 1 large shallot
  • 28 oz. canned peeled tomatoes
  • 6 oz. tomato paste
  • 13.5 oz. full-fat coconut milk
  • 2 tbsp Tuscan or Italian Seasoning
  • 1-2 tsp salt
  • 2 cups vegetable broth
  • 2 tbsp balsamic vinegar
  • 2 tbsp coconut sugar

For the Pesto Grilled Cheese Croutons:

  • butter
  • pesto
  • sliced sourdough bread
  • cheddar cheese


  • Preheat the oven to 450. Wash & slice bell peppers so that you can lay them out on a foil-lined baking sheet. Brush with a small amount of avocado oil and roast for 10-20 minutes (this will depend on your oven) until slightly charred. You can also char them over an open flame if that’s an option.
  • Remove red bell peppers and once slightly cooled, slice the strips into chunks. This is all going to be blended, so it doesn’t need to be perfect.
  • Carefully slice the white parts of your leek into rings and rinse them in a colander (leeks hold a lot of dirt in between their layers). Set aside to dry.
  • Roughly mince garlic and shallot.
  • Heat a large pot over medium heat. Add a tablespoon of oil to the pot and allow to heat for another minute. Sauté the leeks and shallot until softened, about 5 minutes, stirring frequently.
  • Add the minced garlic and tomato paste and sauté for another 30 seconds.
  • Add the canned tomatoes, chopped red bell peppers, broth, coconut milk, seasonings, balsamic vinegar and coconut sugar. Bring to a boil, turn to medium-low and simmer for 30 minutes covered, stirring occasionally.
  • Using an immersion blender (or transfer soup to a blender in batches), blend the soup to desired consistency. Taste for seasoning adjustments.
  • To make the grilled cheese, smear two slices of sourdough bread with butter on the sides that will touch the pan. On the other side, spread a bit of pesto. Layer slices of cheese and build the sandwiches.
  • Heat a skillet over medium heat and melt a tablespoon of butter. Add the sandwiches to the pan and cook until golden brown on one side.
  • Flip the sandwiches and cook on the other side until golden brown. Turn heat down slightly and cover with a lid if needed to melt the cheese.
  • Serve soup with a pesto swirl and sliced pesto grilled cheese croutons on top.
