Heat Coconut Oil in a high sided pan. Saute onion, ginger, garlic, and fresh turmeric over medium high heat until translucent. The turmeric will give a yellow/orange color.
Add in the Sweet potatoes and carrots. Cook for a couple minutes until they begin to soften. Then, fold in the lentils and stir until well coated. Add spices at this time and mix well.
Add vegetable broth or water and bring to a simmer. Cook until the lentils get soft. Add more liquid if needed. Continue cooking until all liquid is absorbed and all ingredients are soft. Add in tomatoes at this point.
Fold in the spinach and let it wilt down. Stir to mix well. Season with salt and pepper.
Allow to cool. Take 1/3 of the mix and puree it in a food processor. Fold it back into the mix. Form the mix into patties. Heat in an oven or pan before serving.
Spray bread slices or buns with pan spray. Sear on a grille or pan to toast. Place the "burger" on the bread and serve with your favorite accompaniments.
