Heat the oil in a large Dutch oven over medium heat. Add the onion, celery, and carrot and cook, stirring occasionally, until softened, about 7 minutes. Add the garlic and cook for 1 minute, until fragrant.
Stir in the canned tomatoes, scrapping up any browned bits from the bottom of the pan to deglaze. Add the broth, barley, lentil, curry powder, ground coriander, black pepper, and bay leaves. Stir to combine.
Bring the mixture to a boil, then reduce the heat to low. Cover and simmer for 30-40 minutes. Turn off the heat.
Taste and adjust the seasoning with salt as needed. Stir in the lemon zest. Serve with a squeeze of fresh lemon juice, and chopped cilantro, to taste.
Let the barley lentil soup cool to room temperature. Store it in an airtight container in the fridge for up to 4-5 days. You can also freeze it for up to 3 months and reheat until hot before eating.
