in a large pot, cook bacon on medium heat until browned, but not crispy.
When bacon is cooked, remove from pot and set aside to cool. Add the chopped onion, garlic, optional butter, and sweet peppers to the bacon grease and saute for 4-5 minutes.
Add water, chicken stock, Italian herbs stock, crumbled bacon, salt and pepper followed by the package of pre-cut collard greens. Bring to low boil or medium simmer.
Cook for approximately 30-45 minutes or until greens are tender to your preference.
When collards are tender, add vinegar. Turn off heat and stir well.
Allow collards to rest for 5-10 minuets before serving.
