Pear slow cooker chicken

I have a pear that is a little too far gone to eat. We also over bought ginger so I'm going to give this recipe a bash: 

• 1 tbsp olive oil
• 2 tbsp butter
• 1 pear
• 1/2 yellow onion
• 1tbsp ginger
• 1 cup chicken broth (will prob substitute something else lying around) 

pop in slow cooker for like 6 hours
