This veggie hummus sandwich is a simple, plant-based option to add into your lunch rotation. Warm, roasted sweet potato lends a hearty and comforting feel to this vegetarian recipe. Add avocado and a few simple vegetables to get a low-effort, ultra satisfying meal in 30 minutes.
With roasted sweet potato, avocado, and pickled onion, this is no ordinary veggie hummus sandwich. The warm element makes this a lunch you can easily crave any time of year, winter included.
You'll usually see hummus sandwiches with typical sandwich fixings, like lettuce, tomato, and onion.
To kick things up a notch, this recipe incorporates warm roasted sweet potato, avocado, cucumber and fresh basil. Include optional pickled red onion (you can find a recipe in my Quick Pickling Guide) for even more flavor and texture.

This is a basic rundown of how to make this sandwich. You can find more detailed instructions in the recipe card at the end of this post.
Roast sweet potato.
Spread hummus on bread and top with the roasted sweet potato.
Add the rest of the vegetables and close the sandwich.
Hint: Try your best to cut the sweet potato into slices of equal thickness. This will help it cook evenly and prevents overcooking/burning thinner areas.
Need to make a substitution? Here are a few ingredients that can be easily swapped.
- Spinach: instead of spinach, you can use romaine lettuce, microgreens, or any sandwich greens you like.
- Pickled red onion: substitute thinly sliced raw red onion or another pickled vegetable, such as pickled radishes. Or feel free to omit.
- Gluten free: use gluten-free bread, and confirm the hummus you’re using is gluten-free.
A few ideas for changing things up with this recipe:
- Spicy: Add your favorite hot sauce or chili crunch.
- Pita: Stuff the sandwich filling into a pita instead of serving on bread.
- Lentil spread: Try this Creamy Roasted Red Pepper Lentil Dip as a sandwich spread in place of hummus.
- Knife and cutting board: To slice vegetables.
- Baking sheet: If needed/preferred, you can cook the sweet potato in an air fryer instead of oven. See the "air fryer" note in the recipe card for instructions.
This sandwich tastes best fresh. It's when you'll still get the warmth of the sweet potato and won't have any discoloration with the avocado.
If needed, you can store the prepared sandwich in an airtight container and refrigerate up to two days.
There is a lot of room for customization for this recipe. If there's a particular veggie you don't have, feel free to leave it out. Add more or less of the toppings to suit your tastes.
Common sandwich vegetables include lettuce, tomato, onion, and pickles. Other vegetables that work well on sandwiches are avocado, sweet potato, eggplant, and cucumber.
