Spicy Tuna Melt With Caramelized Onions

1. 1

   Peel and slice the shallots. Blanch the pearl onions in a pot of boiling water. Let the onions cool before popping off the outer layers. Slice the onions.

2. 2

   Put about a tablespoon of butter and a drizzle of oil in a skillet on low heat. Add the sliced shallots and onions with a pinch of salt. Let them sweat for a while, up to an hour. The onions will get soft and brown. They get sweeter and better the longer you let them caramelize. If you just can't take it any longer, throw in a big pinch of brown sugar to speed them up.

3. 3

   Meanwhile cut a baguette into two pieces for the sandwiches, about 6 inches each. Slice each piece of bread in half vertically. Scoop out some of the inside of the bread to make room for the filling.

4. 4

   In a bowl, use a fork to mix tuna, mayo, mustard, Sriracha, a drizzle of olive oil, and some pepper. Taste to see if you'd like to add more of Sriracha or something else. Mix in the chopped scallions.

5. 5

   Turn on the broiler.

6. 6

   Spread mustard and a bit more Sriracha onto the slices of bread. Scoop the tuna into all four slices of baguette. Top with slices of cheese. Cook the sandwiches under the broiler for just a minute or two to melt the cheese.

7. 7

   Top off the sandwiches with the caramelized onions and a garnish of chopped scallions. Serve immediately.
