Brown the ground beef in a large skillet until cooked through. Drain thoroughly and place in the bottom of the crock pot.
Add the seasonings on top of the beef.
In the same skillet, melt the butter then saute the onion, garlic, bell pepper, and jalapenos until the onions are somewhat translucent. Place these on top of the beef in the crock pot.
Add in the tomatoes, beans, and tomato sauce. Mix well.
Heat on low for 4 hours. Taste for seasonings at this point and add more if needed and let cook for a few minutes longer if you more seasonings are added.
