Sandwich making
Bread choices
For this sandwich I used onion rolls to highlight the onion flavor, but any sturdy, flavorful bread will work. Toasting or grilling the bread helps it hold up to the moist hummus.
Great choices include:
- White bread
- Sourdough
- Whole wheat or whole grain
- Hamburger buns
- Hoagie rolls
- Rye
- Focaccia (open-faced works well)
- Ciabatta
- Potato bread
- Dinner rolls for small sliders
- Bagels
If using a bun, lightly butter and toast the cut side in a hot skillet until golden for extra flavor and structure.

Sandwich fillings
Layer on your favorite fillings and enjoy. A classic combination is lettuce, tomato, cucumber, and caramelized onions. Caramelized onions add sweet, savory depth and elevate any simple sandwich. Cook them low and slow in a bit of oil, stirring occasionally; add a splash of water if they begin to brown too quickly. They’re worth the extra time.
Here are more filling ideas to mix and match:
- Cheeses: Cheddar, Gouda, Mozzarella, Provolone, Muenster, Havarti, Swiss, or Parmesan
- Fruit slices: apple or peach
- Black or green olives
- Avocado
- Shredded or sliced carrots
- Red or green bell pepper
- Sprouts
- Fresh spinach leaves
- Sliced red onion
- Sliced hard-boiled eggs
- Sautéed mushrooms
- Sliced cucumber
- Pickles
- Roasted red peppers
- Coleslaw
- Mash of cooked sweet potato
- Roasted cherry tomatoes

Bread spreads
Don’t forget spreads to add moisture and flavor. Try:
- Mayonnaise
- Mustard
- Garlic & herb cheese spread
- Pesto
- Roasted red pepper hummus
- Jalapeño and avocado hummus
- Tzatziki
- Pineapple-serrano hummus
- Honey mustard
- Cottage cheese ranch
- Mashed avocado
- Peanut or almond butter
- Strawberry-balsamic goat cheese spread
