Heat your dutch oven on medium heat, add oil and then onions. Stir constantly and cook for approximately 3 minutes until onions begin to soften.
Add in minced garlic and chicken and cook another 5 minutes.
Add chicken broth, wine, spices, peppers, beans and corn and bring to a boil.
Reduce heat to low and simmer for another 30 minutes.
In a small bowl whisk together milk and flour. Add to the chili by pouring mixture through a mesh strainer to insure there are no clumps. If making ahead of time turn off the heat, let cool and refridgerate until dinner. You will need approximately 15 minutes to reheat the chili.
As you heat the chili will thicken up. Taste and season with extra salt and/or cayenne if you like it spicy. Add additional broth if your chili gets too thick.
Garnish with favorite toppings just before serving or let your family add their own.
Optional toppings: fresh cilantro, shredded cheese like monterey jack or old cheddar, diced jalapeños, tomatoes, whatever you like.
