In a large pot, mix the lentils, rice, celery, and water, with salt and pepper if desired. Heat on high until it comes to a boil, then lower to a simmer until the rice and lentils are tender, about 50 minutes for brown rice.
In a blender, mix all the dressing ingredients and process until smooth.
In a large pan, heat the olive oil over medium-high heat. Add the onion and garlic and cook for 5 minutes until it starts to brown, stirring often.
Add the greens and cook for about 5 more minutes until the greens wilt but are still a bright green color. Taste and adjust for seasoning, adding salt and pepper if desired.
Assemble your bowls: lentils and rice on the bottom, then a scoop of greens, then a generous drizzle of goddess dressing. Feel free to throw on a few cranberries for color if you like. Enjoy it hot!
