I had set out the English muffins and half-a-jar of homemade pizza sauce to thaw. She used a paring knife to cut the mushrooms. She decided to slice the mozzarella instead of grate it (smart girl). I explained the toaster oven to her.
I contributed popcorn, baby carrots, and ginger beer to the meal. It was simple and satisfying, the lesson and the meal. It's nice to have another worker in the kitchen.
