In a large pot or medium heat, add the oil, cumin, cinnamon, and black pepper. Cook for 30 seconds, stirring often (to toast the spices). Add in the farro, garlic, and ½ tsp salt and stir to coat for about 30 more seconds..
Add the water, tahini, soy sauce, and stir to combine. Stir in the veggies, greens, lentils, and remaining ½ teaspoon salt.
Bring to a boil over high heat, then give it a stir and submerge the veg and kale into the liquid. Reduce the heat to medium-low and simmer for about 3 minutes, stirring occasionally, or until the liquid is reduced a bit (you want it saucy, but not watery. It will thicken up as it sits). Stir in the lemon juice.
Serve topped with fennel slaw and black pepper.
