Indoor grilled summer veggie sandwich – delicious summer grilled veggies (grilled indoor) made into a sandwich that everyone can enjoy on Labor day weekend!
I think a lot of people equate Memorial day as the beginning of summer and Labor Day as the end of summer. During this time, people hang with their family and friends to grill in the backyard and enjoy each other’s company with good food.
I cannot think of anyone who doesn’t like grilled food. When food meets grill, some sort of amazing magic happens and it just tastes absolutely delicious.
Since moving to LA, grilling in the backyard is no longer an option sadly. Our apartment does have a grill but I just feel weird using the grill not knowing who cooked what and when it was cleaned. So I turned to my trusty cast iron pan with grill marks! The good thing about using this method is I can cook all these delicious vegetable in the comfort of air conditioning 😉
My Indoor Grilled Summer Veggies:
- My Indoor Grilled Summer Veggie Sandwich is a vegetarian recipe. However, veggies are a great side dish for any meal. This would make a fantastic side for steak, sausage, chicken, or as is!
- Since this dish is meant for Labor Day gathering, I use summer vegetables like zucchini, yellow squash, pepper, and eggplant.
- Although I’m making these indoor, you are more than welcome to grill outside. I’d only suggest the cooking time to be a little shorter assuming your grill is hotter than my cast iron pan.
- These grilled vegetable really captures the vibrant color and flavor of the summer!
5 Ways to enjoy my indoor grilled vegetables:
- Of course, make a sandwich (recipe below) and serve it as a meal itself or share it with others as an appetizer.
- Make a veggie wrap.
- Great topping for quinoa bowl/buddha bowl.
- A great addition to your salad.
- Make a grilled veggie pizza.
I didn’t just make an ordinary sandwich but I used sun-dried tomato focaccia bread with a healthy smear of vegan pesto! As I was making this, it was hard to stop eating and make the rest of the sandwich. It was that good!
So how about firing up your grill or cast iron pan (in my case) and make these delicious summer veggies for an amazing sandwich to celebrate Labor day weekend with your loved ones?!
Happy eating, my friends!

For sandwich
- Cut the focaccia bread horizontally with a bread knife.
- Smear about 1-2 tablespoons of pesto of your choice on both sides of the bread.
- Layer the grilled vegetables on top of the bottom part of the bread.
- Top it off with the focaccia bread and cut it into a little slider size. Secure with a toothpick so the vegetables won’t slide off of the sandwich.
Notes
- If you are using an outdoor grill, once you flip the vegetable the first time, brush the veggies with marinade and sprinkle some salt and continue to cook for an additional minute or two.
- The cook time on the outdoor grill depends on how cooked you’d like your vegetable and also the temperature of the grill. I personally like my veggie on a slightly crispy.
- The cook time for this recipe is longer than most of my recipes. That’s because I’m cooking lots of vegetables on a medium-size cast iron pan. I had to cook double and triple batches. Feel free to use a bigger pan if you have them.
- You can easily make more of the sandwich if you’d like. There will be plenty of grilled vegetables left. They are a great side dish to any grilled food.
