Preheat the oven to 400F. Drain and rinse the lentils and chickpeas, then spread out on a large sheet pan. Pat dry with a paper towel or clean dish towel.
Drizzle with olive oil, salt, and pepper, tossing to coat well. Roast at 400F for 20 minutes, stirring halfway through. Continue cooking an additional 5-10 minutes, or until the lentils are crispy.
Meanwhile, dice the sweet potato into ½-inch cubes. Slice the pepper into ½-inch strips and cut the broccoli into florets.
Add the sweet potato and vegetables to a large sheet pan. Drizzle with 1 tablespoon of oil, oregano, basil, parsley, dill, onion powder, salt, and pepper. Toss to coat.
Roast at 400F for 30-35 minutes, stirring halfway through. It is ready when the sweet potato is tender and the vegetables are browning.
To make the sauce, whisk together the tahini, apple cider vinegar, maple syrup, and 2 teaspoons soy sauce in a small bowl. Adjust to taste, adding extra soy sauce as needed. Add water, 1 tablespoon at a time, to thin to a drizzle (depending on the brand of tahini you may not need to add any water.)
Assemble bowls by topping the sweet potato and veggies with the lentils and chickpeas and a drizzle of maple tahini. Enjoy!

Notes
Seasonings: This is a homemade Greek seasoning-inspired blend. Feel free to use 1 tablespoon of Greek seasoning for a similar result.
A note on timing: I roast the lentils/chickpeas and sweet potato/veg separately because my oven isn't large enough to fit two large sheet pans. If you have a larger oven or a convection oven then you can roast them at the same time and this will cut down on 30 minutes of cooking time.
Lentils cooked from dry work well here, but the recipe is written for canned lentils for convenience. If cooking dry lentils, I recommend roasting the veg first while the lentils simmer.
How to cook lentils: To cook a similar amount of lentils from dry, add a heaping half cup of dry lentils to 1 ½ cups water or vegetable broth with a pinch of salt. Bring to a boil, then reduce to a simmer and cover. Cook for 18-20 minutes, or until tender. Drain off excess liquid.
