A superb little sardine appetizer with lots of little sardines (and piquillo peppers).
Total Time: The time it takes to toast the garlic toast, if you've already made the pickled onions, which you should have.
1. There are many suggested variations on how best to pickle red onions. What is one of them? This is! Mostly what we're talking about here is a mixture of thinly sliced red onions, apple cider vinegar, salt, sugar, warm water. Let it sit. Be patient. You can store them in the refrigerator for a few weeks, easy. Use them for all sorts of things. Tacos, perhaps.
2. Make garlic toast. You probably have a favorite way of doing this. No? Here's how Rachael Ray makes garlic bread.
3. Place the sardinillas and piquillo pepper slices on top of those pieces of garlic toast, the pickled onions on top of that, and over it all give a few turns of the black pepper grinder.
