Greens: Any greens would taste great in this bell pepper sandwich! Try lettuce leaves, alfalfa sprouts, kale, spinach, or mixed greens for a fresh crunch.

Veggies: Sub tomatoes and avocado for cucumber slices, radishes, onion, mushrooms, pepperoncini, or even jalapenos for a bit of heat!

The steps are simple, and I’m outlining them below but be sure to scroll to the bottom of the page to view the full, printable recipe card.

STEP 1 – PREPARE PEPPERS

Grab your bell pepper, rinse it thoroughly, and pat it dry. Then cut off the stem, turn it upside down and cut it into halves or thirds lengthwise, using your knife to slice along the “seams.” Pull the cut sections apart.  Clean out the middle to remove the seeds.

STEP 2 – ADD CONDIMENTS & VEGGIES

With the hollow side of the pepper facing up, spread on the mayo and dijon as liberally as you’d like. Then add the arugula and tomato slices.

STEP 3 – ADD PROTEIN, CHEESE, & AVOCADO

Next, add the pastrami and top it with the tempered brie. Season by sprinkling on some salt, fresh cracked pepper, and Everything Bagel seasoning. Then add some creamy avocado slices.

STEP 4 – ASSEMBLE & ENJOY

Now it’s time to finish off your delicious bell pepper sandwich! Put the other side of the bell pepper on top, press down firmly, and cut it in half.

Grab some extra napkins, and devour. Enjoy!

FAQ

What kind of bell peppers should I get to make a bell pepper sandwich?

Any kind of bell pepper will do. Just be sure that it’s at least medium to large in size, depending on how big you’d like your sandwich to be. 

It’s also helpful to get bell peppers that are full, have good proportions, and are as “picture perfect” as possible. In other words, they shouldn’t be dented inwards, flattened out, or have any visible bruises. 

Can I make this bell pepper sandwich vegan or vegetarian?

Absolutely! Just leave out the pastrami and add your favorite vegetarian/vegan ingredients.

Try adding some grilled eggplant or portobello mushrooms, roasted zucchini, and/or hummus for a delicious vegan take on this sandwich. 

Can I make this bell pepper sandwich ahead of time?

Yes, you can! Since you aren’t using bread that can get soggy, you can actually assemble these sandwiches the night before and store them in an airtight container in the fridge. Just remember to take it out of the fridge an hour before you plan to eat it so that the brie has time to soften up. 

Storage

Store any leftover bell pepper sandwich in an airtight container in the fridge for up to 1 day.
