1 tsp. butter
1 1/2 C. vertically sliced onion

3/4 C. chopped Canadian bacon
6 C. (1-inch) cubed sourdough bread (about 12 oz.)

Melt butter in a large nonstick skillet over medium-high heat. Add onion, and sauté 4 minutes. Reduce heat; cook 10 minutes or until golden brown, stirring occasionally. Add bell pepper; cook for 1 minute. Remove from heat; stir in bacon. Arrange 3 C. bread in an 11 x 7-inch baking dish coated with cooking spray; top with half of onion mixture.
