Add oil to a large pot over medium heat. Add chopped onions and garlic, and cook until onions are translucent, around 3 minutes. Add veggie crumbles and cook for 3 to 5 minutes.
Add beans, tomatoes, and corn. Stir to combine. Bring to a simmer, then reduce heat to medium-low and cook for 10 to 20 minutes. If using chili-ready tomatoes and beans, you may not need to add more chili powder. Taste and determine at this stage. If more is needed, add one tablespoon at a time. If you're not using chili-ready tomatoes and beans, you may want to add up to 3 to 5 tablespoons of chili powder based on your taste preferences.
Serve warm with cornbread, crackers, or your favorite crusty bread.
If you don't have chili ready tomatoes, simply used diced tomatoes and add additional chili powder to taste.See post tips for ideas on veggie crumbles.
