1) Season chicken well with salt, pepper, garlic powder, and onion powder. Place in the crock pot. Top with chopped onions and garlic.
2) In a saucepan, melt butter. Stir in flour, chicken broth, and milk. Pour into crock pot. Add salt and pepper. Cook on low for 8 hours.
3) 1-2 hours prior to serving. Shred chicken and return to pot. Add steamed veggies (I steam them in the bag in the microwave.) Roll biscuits into small balls (2 per biscuit) and add to crock pot. Continue cooking until biscuits are firm.
