Grilled Chicken Eggplant and Zucchini on a Bun

Grilling vegetables is so good and works great on this sandwich! This post is sponsored by Windsor Salt.

With grilling season in full force, I look for anything that I can grill. While meat is most common, I do really enjoy grilling vegetables. Zucchini, eggplant and peppers are ideal vegetables to be grilled, and they are excellent tossed into pasta salad with feta cheese, as toppings for a pizza or eaten just on their own. One other option is to use them for a sandwich or on a bun like this recipe.

I made a marinade that is used both for the chicken and brushed on the vegetables while they are grilling. Marinades are a great way to boost the flavour of food and there are key elements to any marinade, including oil, acidic ingredients like vinegar or lemon juice, spices, herbs and more. Salt is also a key component of any marinade and I used some table salt from Windsor Salt. Since I was born in Windsor, Ontario, I have always been partial to purchasing salt from Windsor Salt! Windsor Salt has just recently had a brand refresh with a new logo and packaging. While it is a new look, it is still the same great salt product!

This marinade is essentially an herb and garlic marinade and that works very well with both the chicken and veggies. On top of that, some pesto is spread on the bun to further add a depth of flavour.
