Warm the oil in a large pot over medium heat. Sauté the onions until they're translucent and soft, approximately 7 minutes.
Add all remaining stew ingredients. Bring pot to a boil, then reduce to a simmer. Simmer for 20 minutes.
While the stew is simmering, press your tofu with a tofu press. (Ensure most of the water is removed so that your stew doesn't taste watered down).
In a skillet, warm some oil. Add the tofu block and mash with a fork until crumbled. Sauté for 8 minutes, or until golden brown.
Add your crumbled tofu to the stew pot and stir to combine. Cook another 5 minutes.
Serve and garnish with lime, jalapeño, green onion and tortilla chips.
