The taco consists of a flour tortilla filled with sweet potatoes and generously topped with cheddar cheese, guacamole and salsa. I love the use of sweet potatoes because it makes for the perfect sweet/savory combo. Hot sauce is available for you hot heads. Honest Tom's is a new addition to Philly's growing food truck scene and it offers a breakfast taco in the morning and a meat and a vegetarian taco for the afternoon lunch crowd. They keep things simple, delicious and fresh.
