Grilled Summer Squash and Red Onion with Feta - Memorial Day is Grilling Day!

Memorial Day marks the beginning of summer vacation, peak season at amusement parks, the summer box office, the opening of campgrounds, and most importantly - the high season of barbecue! Just two weeks away, it’s time to get your menu ready for this hallowed day of feasting because Memorial Day is Grilling Day! For a lovely side dish that will not disappoint, try Grilled Summer Squash and Red Onion with Feta, featuring roasted veggies topped with tangy vinegar and garlic and salty feta.

Pulling from a technique called escabeche, we will take a different approach for this dish of marinating after grilling. After grilling the squash and red onion over medium-high heat until beautiful grill marks form, arrange them on a serving platter with feta and bay leaves. Cover the veggies with a marinade of white wine vinegar, garlic, and olive oil and let it sit for at least 15 minutes before serving. The acid will preserve and combine for a beautiful pairing of texture and flavor. Say goodbye to soft, bland squash this summer and hello to amazing new recipes because Memorial Day is Grilling Day!
