Today's lunch is barley with Mint-Pistachio Pesto (a Your Best Recipe with Mint finalist!) and crumbled feta. In Amanda's words: "Kids love mix-ins! And watermelon. Because it's summer, and kids deserve to eat lots of watermelon when it's in season."

We've got a bevvy of Walker-and-Addie standbys in today's lunch snapshot: ham and cucumber sandwiches, a big favorite, paired this time with farmer's cheese and a chimichurri sauce that you'll be seeing on FOOD52 sooner or later.

This edition of Amanda's kids' lunch is brought to you by Amanda's CSA haul: pattypan squash and broccoli (cooked in lots of olive oil and a little bit of water over high heat) with sour cream cilantro sauce and goat cheese, plus Greek yogurt with dark honey and blueberries for dessert.

How are you cooking up summer's abundance of summer squash?
