Best Chili Ever

Another recipe I've improved on over the years. It just keeps getting better all the time. Sorry guys, but I don't measure. I'll try my best to give a rough idea.

• Ready In: 1 hr 20 mins
• Serves: 10

Ingredients

• 2  lbs lean ground beef
• 1 -2  cooking onion
• 1  green pepper
• 2 -4  portabella mushrooms or 2 -4  mushrooms, of choice
• 2  stalks  chopped celery
•  chopped garlic
•  salt and pepper
•  Worcestershire sauce
•  beer
• 2 -3  tablespoons cumin
• 4 -5  tablespoons chili powder
• 1  tablespoon  dried chili pepper flakes
• 2 (28 ounce) cans diced tomatoes
• 2 (19 ounce) cans  drained kidney beans
• 2 (14 ounce) cans  brown  pork and beans in tomato sauce or 2 (14 ounce) cans  maple  beans
•  taco chips (optional)
•  shredded cheddar cheese or  cheese, of choice
•  chopped green onion
•  sour cream

Directions

1. Brown ground beef in large pot and drain grease. Stir in fresh diced veggies and cook till tender. Add chopped garlic, Worcestershire, and about half bottle or more of beer. Allow to simmer down some and stir.
2. Drain kidney beans and add with diced tomatoes, brown beans and spices. Give an occasional stir and let simmer for at least one hour. The longer it stays on the stove simmering the better.
3. •Optional ideas: Add grated cheese to top off chili with crushed taco chips, chopped green onion and a dollop of sour cream, or just try one or two of these extras of your choice.
