Place the 2 TBS of butter into a large pan or skillet over medium heat.
Let the butter melt.
Add the green onions, celery, carrots, onions, and garlic to the melted butter. Let it cook for about 4-6 minutes stirring occasionally.
Once the carrots get slightly soft, (won’t take long if you grated them) add the 1/3 cup of Jeff’s barbecue sauce to the vegetables and mix together well.
Note: After about 4 minutes, if the carrots are not soft, cover the vegetables with a lid for a couple of minutes to help speed things along.
Set the vegetable/sauce mixture aside to cool for about 10-15 minutes. It will need to be room temperature or less before adding it to the meat.
