This is similar to a dish served at a restaurant in San Juan Bautista, which is the only reason I can think of that it's called "Mission" chicken. The bacon and smoked paprika give it a nice smoky flavor my husband likes.....It's quick and easy,and dinner in one pot --that's what I like about it. ***NOTE: Sage grows wild in California, so it was a common seasoning. If you don't like sage, don't use it! Other herbs work well also.
