Heat oil in saucepan on medium-high. Crumble in beef. Sprinkle with chili and garlic powders, salt and pepper. Using a fork, stir often to keep beef crumbly until no pink remains, approx. 5 min. Add tomatoes, mushrooms, corn and brown sugar. Bring to a boil, stirring often. Reduce heat to medium-low and partially cover. Simmer, stirring occasionally (approx. 10 min.). Stir in kidney beans and cook until hot (approx. 5 min.). Remove from heat and stir in basil. Let stand for approx. 10 min. Optional: Serve in bowls topped with grated cheese of your choice, with tortilla chips on the side for dipping.
