Q: Is the Egg, Pesto & Mozzarella Sandwich vegetarian?

Yes! It's a lacto-ovo vegetarian option—made with eggs and dairy (like mozzarella and other cheeses), but no meat or meat by-products. Official ingredients list microbial enzymes (vegetarian-friendly) in the cheeses, so no animal rennet is used. Perfect for vegetarians looking for a hearty, meat-free breakfast!

Q: What kind of bread is used?

It's served on a toasted Cheddar and onion bialy (a soft, flavorful roll similar to ciabatta). The bun has white cheddar cheese and onions baked right in, giving it a savory, cheesy crust with subtle onion notes that pairs amazingly with the pesto and egg.

Q: Is this sandwich high in protein?

Definitely— it packs 21g of protein per serving (around 390 calories total), making it one of the top high-protein vegetarian picks on the Starbucks breakfast menu. Great fuel for busy mornings!

Question 3

Is the pesto made with nuts?

Accepted Answer

Starbucks' kale pesto is nut-free! It's a blend of kale, basil, parsley, garlic, lemon juice, and vegetable oils (canola and olive)—no pine nuts or other tree nuts listed in the official ingredients. That said, always double-check the label in-store or on the Starbucks app/website, as cross-contamination is possible due to shared equipment.

Can I customize the sandwich?

Accepted Answer

Since it's pre-assembled and warmed to order, you can't remove or swap core ingredients (like the kale in the frittata or the pesto spread). But you can easily add extras like Sriracha, avocado spread, or other available toppings for a personalized kick!
