Whole 30 Day 5, Grilled Flank Steak and Zucchini with Chimichurri

Jump to Recipe

Well, the weather did cooperate and we were able to bring a taste of summer to January. If you’re not up for a BBQ right now I can hardly blame you, but file this one away for warmer days because it is a delicious meal.

Grilled Flank Steak and Zucchini with Chimichurri, Roast Potatoes, and Salad

The chimichurri is the star here, packed with flavor and not at all complicated to make. And it gave me a chance to pull out my mezzaluna knife! I bought it from the greatest old hardware store when I lived in North Beach half a lifetime ago. I don’t use it very often, but it is perfect for mincing a pile of fresh herbs. This is one of those recipes you should play with, substituting the cilantro for another herb depending on the dish.

Slice squash about 1/4 inch thick

We added a few roast potatoes and mixed greens tossed with olive oil and balsamic to our dinner. I really like a basic salad as well as a cooked vegetable with dinner, because most days I have a heartier salad for lunch. (And that is not just when I am on the Whole 30.) Tonight’s dinner, just like the grilled chicken from a couple of nights ago, will provide perfect salad fare for tomorrow.

Salad with grilled chicken, tomato, avocado, kalamata olives, toasted pine nuts, and green onions made a great lunch today. I whipped up a quick balsamic vinaigrette to top it off.

I will be back tomorrow with the long promised fritatta recipe from Jason! See you then…
