Bring a medium pot with water to boil.
Add orzo and cook according to package directions.
Meanwhile, chop zucchini and toss with corn and olive oil. Season with salt and pepper.
Place zucchini and corn in a fine mesh grill pan and grill over medium-high heat for 8-10 minutes. Note: if you are using corn on the cob, you can just brush it with olive oil and grill the whole cob on the grill, about 3-4 minutes on each side, turning twice. Then cool the corn on the cob and cut off kernels.
In a large bowl, combine orzo, zucchini, and corn.
In a small mason jar, combine olive oil, lemon zest, lemon juice, garlic, and salt. Screw on lid and shake well until combined.
Pour over orzo and veggies, and stir to combine.
Garnish with green onions and goat cheese.
Serve and enjoy!
