Stir in garlic, cumin, thyme, turmeric, salt, and pepper. Cook for another 1-2 minutes until fragrant.
Add lentils and broth to the pot. (If using collagen powder, add it now and stir well.)
Increase the heat to high and bring the mixture to a boil.
Reduce the heat to low, cover, and let it simmer for 35-40 minutes or until the lentils are tender.
Stir in the mushrooms and kale. Cook for an additional 3-5 minutes until tender.
Serve warm.
