Heat the olive oil in a large pot over medium heat. Add the onion, carrots, and celery and cook for 5 minutes until the vegetables begin to soften.
Stir in the mushrooms and cook for another 4 minutes until they release their liquid and start to brown.
Add the garlic and thyme and cook for 1 minute until fragrant.
Pour in the freekeh and vegetable broth. Bring the mixture to a boil, then reduce the heat to low and simmer for 20 minutes.
Add the chickpeas and kale. Continue simmering for 10 more minutes until the freekeh is tender and the kale wilts.
Season with salt and black pepper. Stir in the fresh parsley just before serving.
