• Scallions - Chives also work.
• Spicy Mayo - You can either make your own or use the recipe below! If you don't like spicy mayo, just leave it off.
• Smashed Avocado - I love smashed avocado with a little bit of lime juice and salt -- Simple but perfect. If you don't like avocado, just skip this step.
• Tostada Shells - I buy these from the store but you could def make your own or swap them out for soft tortilla shells.
• Toasted Sesame Seeds - Totally optional and can be left off if you don't have any. They're mostly for a finishing texture.
