Step-By-Step Directions

1

Prep the veggies

Wash zucchini and squash, slice into 1/4-inch strips, brush with olive oil, and season with salt and pepper.

2

Make the Drizzle

Blend basil, garlic, olive oil, honey, lemon juice, and zest until smooth.

3

Grill the veggies

Preheat grill to medium, cook slices 3-4 minutes per side until tender and marked.

4

Arrange and Serve

Arrange grilled veggies, drizzle with sauce, sprinkle with feta, and garnish with basil and lemon zest.

Pro Tips

  • Uniform Slices: Slice the zucchini and squash evenly to ensure they cook at the same rate. Aim for 1/4-inch thickness for the best balance of tenderness and grill marks.
  • Preheat the Grill: Make sure your grill is fully preheated before adding the vegetables. A hot grill will give you those beautiful, charred marks while keeping the veggies from becoming too soft.
  • Use Fresh Herbs: Freshly picked basil will give your sauce the best flavor. If possible, use basil harvested the same day for the brightest, most aromatic result.
  • Serve Immediately: This dish is best enjoyed fresh off the grill, while the veggies are warm, and the feta is slightly softened from the heat.

FAQs

Absolutely! You can substitute or add in other summer vegetables like eggplant, bell peppers, or even asparagus. Just adjust the grilling time accordingly.

No problem! You can use a grill pan on your stovetop or roast the vegetables in the oven at 400°F for about 15-20 minutes, flipping halfway through.

Yes, the sauce can be made up to 24 hours in advance. Store it in an airtight container in the refrigerator and give it a good stir before using.

Fresh basil is recommended for the best flavor, but if you must use dried, reduce the amount to about 1-2 teaspoons and mix it into the sauce a bit earlier to allow the flavors to meld.
