Escarole does not go well on top of Mexican pizza. Just in case you didn't know that already.
I made a Mexican pizza last night, topped it with some shredded zucchini (putting that stuff everywhere!), and then must not have grabbed the right head of green stuff out of the fridge, because boy, was that pizza bitter! Luckily, it was easily saved by simply removing the greenery.
On a separate note, apparently my pup, who does not eat vegetables, has discovered a new affinity for green cherry tomatoes from the vine. He came in with a yellow head earlier this week, and then the hubs caught him in the act yesterday morning. Silly dog.
