This pesto sandwich recipe with roasted vegetables is a great way to sneak in some extra veggies for lunch, in a hearty, flavorful, and filling sandwich.
What isn’t made better when sandwiched between two slices of bread? Few things. Very few things. This roasted vegetable sandwich is no exception. Even if the thought of eating something from the vegetable kingdom makes you turn up your nose, this sandwich is so full of layers upon layers of flavor that you not only won’t mind the vegetables, you might even grow to like them.
So, lets talk about those layer of flavor. First, we have the marinade. The best way to add flavor to veggies, is to roast them in a flavorful sauce, like what is often done with meat. The vegetables will soak in even more of the sauce than meat would, and are bursting with its flavor by the end of cooking time. The marinade, which is comprised of balsamic vinegar, Italian herbs, and olive oil, will caramelize on the vegetables and make them sweet, browned, and infused with herb flavor.
The next layer is the pesto sauce. This herby spread will brighten up the sandwich and add a pop or freshness to balance out all the roasted flavor. Pesto is a sauce made of basil, nuts, lemon juice, and olive oil. It can be made in under 10 minutes with a food processor and can be used to add flavor to all kinds of sandwiches.
The last layer is hummus. That’s right, good old hummus joins the sandwich party to add a creaminess that pairs well with the crusty toasted bread.
We have flavor. We have texture. We have one healthy and satisfying sandwich.
Some 101 on how to make that perfect sandwich:
Tip #1: Salt the eggplant.
Eggplant is a tricky vegetable. Most people think that they don’t like it, and that is because they have had it prepared incorrectly. Eggplant has a high water content, and to cook it properly, we have to remove some of that water before roasting. You will want to line a baking tray with a few layers of paper towels, and then place the sliced eggplant on top of the paper towels. Sprinkle one side of the eggplant with salt. Flip it over and sprinkle the second side. Let the eggplant sit for 30 minutes. The paper towels will soak up the moisture that the eggplants give off. Now that some of the water is out, the flavor of the marinade will really soak in. The eggplant will roast up meaty and caramelized, rather than wet and soggy.
Tip #2: Feel the burn.
The roasting time for these veggies is long, and that is because it really develops and increases their flavors. Those slightly burnt edges will add tons of flavor and texture to our sandwich. The veggies might look overdone, but that is when you know they are ready.
Tip#3: Warm as toast.
For the ultimate contrast of textures, creamy, meaty, and crunchy, be sure to give the bread a good toast. You can pull out your handy dandy toaster to get the job done, or if you are making more than a sandwich or two at a time, you can use your oven. Brush both sides of the bread with olive oil and line them up on a sheet tray. Place them in an oven set to high broil until they are golden brown. Flip the slices over and repeat. Just be sure to watch them closely – they can go from a perfect toast to burnt toast in a couple of seconds.
