Preheat your oven to 400°F and line a baking sheet with parchment paper.
Cut the carrot into half-moons and break the broccoli into bite-sized florets.
Place the carrots and broccoli on the baking sheet, toss with a tablespoon of vegetable broth to prevent sticking, and roast for 20 minutes until tender and slightly caramelized.
While vegetables roast, finely dice the onion and mince the garlic cloves.
In a medium saucepan over medium heat, sauté the onion and garlic in two tablespoons of vegetable broth for 5 minutes until softened.
Rinse the black lentils thoroughly and add them to the saucepan along with the remaining vegetable broth and dried thyme.
Bring the liquid to a boil, then reduce the heat to low, cover, and simmer for 20 to 25 minutes until the lentils are tender but still firm.
Remove the saucepan from the heat and stir in the nutritional yeast, fresh spinach, sea salt, and black pepper until the spinach has wilted.
Fold in the roasted vegetables and finish the dish with fresh lemon juice and a sprinkle of hemp hearts for added texture.
