This chili spaghetti recipe falls into the category of tummy filling meals that won't break the bank. The simple ingredients start with lean ground beef and light red kidney beans all smothered in a robust homemade chili sauce. After cooking until the flavors have perfectly married, the chili is then tossed with steamy al dente spaghetti. Top it off with a heaping helping of cheddar cheese, a dollop of sour cream and for the finishing touch a sprinkling of sliced green onion for crunch.
