Chicken and mushrooms team up in this easy crock pot chicken marengo. It's a french dish, named for the battle of marengo. In the late springjune 14of 1800, napoleon defeated austrian forces in the northern italian village of marengo. Napoleon purportedly asked his chef to prepare a quick meal with local foods. The original chicken marengo was made with the ingredients he found: chicken, eggs, tomatoes, olive oil, crawfish, and eggs. He created the quick and easy saute, and there are now many variations of the dish. This slow cooker version is made with mushrooms instead of crawfish, and there are no eggs. The dish is also similar to hunter's chicken. It's made with boneless chicken thighs, making it flavorful and easy on the budget. Feel free to saute about 1/2 cup of coarsely chopped onions with the mushrooms and add them to the pot. Diced bell pepper is another flavor option; add about 1/4 to 1/2 cup of sweet green bell pepper to the mushrooms. A 16-ounce jar of spaghetti sauce or italian marinara sauce may be used to replace the diced tomatoes and spaghetti sauce mix. 1/4 cup of sliced ripe olives may be added as well. Serve chicken marengo with hot cooked pasta, rice, or egg noodles.
