Grilled Vegetable Sandwiches with King’s Hawaiian Buns
*This is a sponsored post by King’s Hawaiian. All opinions are mine. I love this company. 
Ah, summer. I’m so glad it has finally started for us!! School got out late this year so it didn’t really feel like we could really DO summer until a week ago. Now our days are filled with swim lessons and keeping cool. And it finally feels right to barbecue everything. I’m not a huge fan of steak though, and I eat a ton of chicken so I wanted to switch it up a little. Grilled veggies are one of my favorite things to eat so I thought, Hey! Why not make them in to a sandwich?!
A quick trip to the store yielded all the ingredients for the grilled sandwich of my dreams!! But you could easily sub out whatever makes your heart happy. Do not switch out these King’s Hawaiian buns though. I’ve never loved hamburger buns but THESE I could eat on their own. Same great taste as their rolls. And super light and airy. While this is a sponsored post, I totally don’t have to make lifestyle changes based on the writing of a post for one company. But I plan to only use these buns for my burgers from now on. Gross regular hamburger buns, consider yourselves replaced!
I really like to play around with different flavors for my grilled veggies. I love how caramely they can get with a good balsamic vinegar and how flavorful they can be with a drizzle of evoo and some fresh minced garlic. But when I came across this recipe for a mustard and herb grilled veggie sandwiches. I knew I had to try them out! I also knew the sweet touch of the King’s Hawaiian buns would be the perfect balance to the tang of the mustard. If you are not a fan of mustard (which I am usually not) then you can still make this grilled vegetables sandwich by using an easy vinaigrette (mix about 1/4 cup of extra virgin olive oil, 1/4 cup good balsamic vinegar, 1/8 tsp salt, fresh ground black pepper to taste, 1 clove garlic minced, 1/2 tsp dried oregano, 1/2 tsp dried basil).
I made the mustard herb sauce and tossed all my veggies in it. They don’t need to really marinade in the sauce, just need to be coated. I also didn’t baste them throughout the cooking process. I’m a lazy cook… Well, my husband usually does the grilling, but I guess I was too lazy to tell HIM to baste them…
Here’s the kicker you guys. So I love In N Out (a pure California treat! So sorry if you have never experienced it. Put it on your bucket list). On their animal style burgers they do something called “fried mustard” where they grill mustard on to the bun. It’s so great! So I decided to try that out on the grill. All you need to do is spread a light layer of yellow mustard on each side of the bun before placing them directly on the heat.
Then you send your husband outside with a whole lotta veggies to grill. And then give him instructions like, “Look pensive. Now really sell it. You ARE summer grilling!” while taking photos of him making your dinner. We just got one of those bbq grill pans, btw and it is awesome!! My husband no longer gives me the stink eye when I give him tiny little pieces of veggie to try to balance on the grill.
Once the veggies are done you are ready to assemble the sandwich. How yum do those crusty mustard buns look?!
Stack the veggies in any order you want. Leave off what you don’t want and put on what you do. The buns will have a nice little crisp edge to them but I felt like I wanted to have a little bit more texture for my sandwich so I grabbed some crispy onion straws.
The taste is tangy and sweet from the mustard and the King’s Hawaiian bun. It feels hearty from the thick cut veggies and fresh from the herbs in the mustard sauce. You can pair it with anything from chips like I did since this was my husband’s night to help with dinner and since he was grilling I didn’t want to have to make anything…lazy. But this would go really well with a salad, baked beans, coleslaw, etc.
I can’t wait to make these again! And a quick side note, the leftover vegetables were fantastic cold the next day!
