The BBQ test is a test for meaning.
The way it works is to pick something important about your life. It could be a personal relationship, your job, a habit. Anything important to you. Pick it and think about it.
Now picture yourself at a backyard BBQ. The weather is perfect, smoke is rising off the grill, and you have a plate of your favorite food. Your friends and family are there. Someone approaches you and asks you about that important thing in your life.
How do you feel?
That's the BBQ test.
