Why a grilled veggie sandwich?
The tags like dairy-free or vegan do not mean that it has to be flavor-free or dull. The vegan dairy-free recipes can be turned into effortlessly bright, refreshing, and energetic dishes.
Proper planning and selecting ingredients are the main factors in deciding whether the dish is fresh or dull. And has nothing to do with the label of dairy-free or vegan.
This grilled veggie sandwich comes together in about 15 minutes from scratch. It is still a vibrant, creamy, and satisfying all-day breakfast dish.
The vegetables
Any vegetable is great to add to this recipe. My choices are but not limited to the onion, bell peppers, tomatoes, avocados, and zucchini. The zucchini in the mushrooms is also great for making this grilled veggie sandwich recipe.
You do not need to go out for grilling in the chilling weather like this. Vegetables can be cooked very quickly when grilled. You can enjoy refreshing grilled vegetables still with the comfort of sitting inside the home.
Avocado is a healthy substitute for cheese in vegan. Opting for a vegan is not meant to compromise on the taste, and this grilled veggie sandwich recipe is proof to support this statement.
Layering the sandwich
We can divide the grilled veggie sandwich layers into two. The first one is grilled vegetables, and the second is fresh vegetables.
- Onion and bell pepper add texture to the sandwich and should always be kept as a basic layer. Grilled zucchini can be added next to two onions and bell pepper. Tomatoes become soft and tender after grilling, so it is best to be on top of grilled vegetables.
- Cucumbers can be eaten raw and should be kept on top of all the ingredients. It has a neutral taste, and it balances all the other flavors. And in addition, it adds rich crunchy to the dish. And it's also an essential cool ingredient to start the day brightly.
We are making a standalone vegan grilled veggie sandwich that does not need any cheese or mayo substitutions. For this recipe, I don't prefer using them at all as this itself is wholesome and creamy. And I bet you will not need cheese substitutes to make it richer. If you still need any, opt for vegan mayo or vegan cheese.
The bread
The choice of bread depends on the choice of your preference for this grilled veggie sandwich. You may also use white, multigrain, honey wheat, crusty French or Italian bread.
I always go with the honey wheat bread as the texture is between the white and the whole wheat bread. Generally, I don't prefer whole wheat bread to make this because it is not firm enough to hold the weight of the vegetables.
Marination for the grilled veggie sandwich
Cut all the vegetables and transfer to a ziplock bag with the extra virgin olive oil, dried oregano, and salt for about 1 hour in the refrigerator. Rich olive oil and oregano flavors will infuse the vegetables and taste extremely delicious when they get grilled. This margination makes the flavors outstanding and tempting. I recommend marinating for at least 15 minutes to 1 hour before grilling.
How do you store the leftovers?
Store the leftover vegetables in a zip-lock bag or an airtight container and refrigerate. This stays good for a week. And to reuse, you reheat in the pan on the stovetop. And you may add fresh slices of cucumber, avocado, or a pickle and relish.
Tips for grilling
- You may use a stovetop griller pan, a portable griller, or a regular griller.
- Vegetables have a different texture and different cooking times. So, the time to grill also varies for each vegetable. Vegetables like zucchini or tomatoes will cook faster than asparagus or eggplant.
- You do not need to be accurate while grilling. The sandwich will be more flavorful even if the vegetables are not done thoroughly.
- You can arrange all the slices of vegetables over the grill and cook them simultaneously. For the first few minutes, cook at a high temperature. Once you start seeing the grill marks, then you may cook at a medium temperature. You can remove the vegetables when they change their color.
