Soak the dry chickpeas in cold water overnight. The second day, drain, rinse, and set aside.
Make the chickpea broth. Add 2 liters of water to a heavy bottom large pan on a medium-low heat, add the bouillon and stir until the bouillon is totally dissolved and then add the rinsed chickpeas and let it cook for 20-30 minutes until the chickpeas are fork tender. If a foam rises to the top of the broth, then remove it with a spoon or with a kitchen paper (as shows in the video).
Season the chopped vegetables with salt and pepper, mix them with the tomato paste and arrange them on baking sheet or a heat resistant dish. Roast the vegetables In a preheated oven at 375 °F for 20 minutes or until the vegetables have softened and are beautifully charred.
In a mini-food processor, blend all the roasted vegetable to a fine paste. Run through a fine mesh sieve if it has any lumps and then add to the simmering chickpea broth. and let it simmer another 5-10 minutes until the vegetable paste is totally incorporated into the broth.
Serve the Halabessa hot in tall glasses with extra wedges of lemon or lime and dry pepper flakes or tabasco sauce.
Nermine's Notes
This soup is best made from scratch with dry chickpeas and NOT the canned ones. Soaking the chickpeas in cold water overnight is a must, before boiling the chickpeas in the broth.
You can possibly downplay the heat by removing the green chili from the ingredients.
