Prepare the lentils. Place the lentils in a mesh strainer and rinse under cold water to clean of any dirt. While rinsing, look through the lentils and pick out any small rocks or imperfect lentils.

Place the lentils into a medium-sized pot over medium heat along with the bay leaf, two cups of water, minced garlic, salt, and pepper. Stir well and bring up to a simmer, then turn heat to low and let simmer, covered, for about 25 minutes or until the lentils are tender. Stir occasionally and check the lentils for doneness while simmering.

Once tender, remove any excess water in the pot then add in the pasta sauce, zucchini, and 1/3 cup of water. Stir well and let simmer together for 5-10 minutes to warm the sauce through.

While the sauce simmers, cook the spaghetti noodles according to the package instructions. Strain and serve with the lentil sauce mixture over the top. Enjoy!
