alton toast (named for inimitable alton brown who created the original version of this recipe) is our go-to breakfast/lunch/dinner/snack when we need something filling and delicious that feels good. it's easy to throw together as long as you keep a couple cans of sardines on hand and have an avocado ripening at home, and it's packed with all the best kinds of fat from fish and avocados. as a bonus, because they're low on the food chain sardines are super sustainable, so you can chow down free from guilt. if you're unsure about canned fish, this recipe will make you a true believer and may even turn you (like us) into an obsessive canned sardine hunter whenever you visit a new grocery store! for the least fishy flavour, try to find small sardines like brislings.
