In dutch oven, brown meat with onions. Drain well and return to pan.
Add tomato sauce, stewed tomatoes, kidney beans, mushrooms, jalapenos, and brown sugar/spices.
Bring to full boil, and reduce heat to low. Cover and simmer for 2 hours to allow flavors to meld, stirring occasionally. NOTE- Cumin, chili powder, and jalapeno amounts can be adjusted to suit your personal taste.
