Here is what the show was about:
"Michael is inspired by his garden and creates a meal with a common ingredient - fresh tomatoes. In the kitchen, he makes a chorus of dishes: roast penne pasta, green salad with tomato lemon vinaigrette, and tomato water martinis."
As you can see, they are calling it a tomato lemon dressing.
