2/3 c. oil
2/3 c. flour

Mix oil and flour together in a four cup measure. Microwave uncovered on high for 6-7 minutes. Stir at 6 minutes. Roux will be a light brown at this time and will need to cook 30 seconds to 1 minute longer, to reach the dark brown color. Add 2 cups onion, 1/2 cup bell pepper and cook on high 3 minutes longer.
