Add the onion and oil into a large, lidded cooking pot. Saute the onion over moderate heat for approximately 3 minutes.
Add the garlic powder, paprika, chili powder, chipotle powder, coriander, oregano, cumin, pepper and no-salt seasoning. Add a few splashes of this beer/stock to deglaze the pan & simmer for 3-4 minutes. Reduce the heat-slightly or add more when the spices are burning in any way.
Stir in the bell and poblano-peppers and the remaining of the beer. Simmer approximately 7 minutes.
Add the soy sauce, canned tomatoes, liquid smoke, maple syrup, salt and water. Loosely lid the pot & simmer about half an hour, stirring periodically.
Stir in the quinoa, lemon juice, corn, black beans and walnuts. Reduce the heat to medium-low, lid the pot & simmer for 50 minutes, stirring periodically. Add enough water to ensure it is the consistency you like as you want to.
Serve and enoy with favorite toppings.
