In a large pot or cast iron pan, heat olive oil on medium heat.
Saute garlic for 1 minute, then add diced onions. Saute for 4-5 minutes, or until onions are translucent.
Add diced red peppers, and saute for an additonal 2-3 minutes.
Add ground turkey and italian sausage and cook until browned. Drain oil and return to stove.
Turn heat to medium high and add half of chili seasoning to turkey mixture (I use the full amount of seasoning but you can add half and add more to your liking if needed).
Add tomato paste to mixture and allow to toast. Be sure to turn frequently to prevent burning.
Reduce heat to medium and add beer. Stir up browned seasoning and meat from the bottom of the pan.
Reduce heat to simmer (low heat) and add beans, tomatoes and brown sugar. You can also add the remaining chili seasoning here to taste. Mix well and allow to simmer for 1 and a half hours.
Remove from heat and serve with your favorite toppings!
