Preheat the oven to 350°F.
Scrub the potatoes and poke each one several times with a fork. Then, wrap them individually in foil.
Place the potatoes in the oven and bake for about 90 minutes or until fork tender.
With 45 minutes left on the potatoes, add water and lentils to a small saucepan. Simmer over medium heat and cover for about 20 minutes. Make sure it's a slow simmer so the water does not vaporize before the lentils are cooked. Check every so often if you still have water in the pan to avoid burning the lentils.
With 30 minutes left on the potatoes, make the chili. Add the olive oil to a skillet over medium heat. Once hot, add the onions and garlic.
Cook until fragrant and the onions are translucent, usually about 5 minutes.
Next, add the beans, diced tomatoes, tomato sauce, chili powder, and bay leaf. Bring to a simmer for 20 minutes, stirring occasionally. Remove the bay leaf.
Unwrap the baked potatoes and cut a slit across the top of each piece.
Slightly fluff the insides of the potatoes with a fork. Spoon chili over each potato and top with vegan cheese, sour cream, green onions, and jalapenos. Enjoy!
