Slice your baguette pretty thinly and chop or grate your dark chocolate.
Lay the baguette pieces out on a cookie sheet and give them a quick spray with olive oil. Toast them up. Don't aim to get them too dark you really just want to heat them up enough to get crispy and warm enough to melt the chocolate.
Working quickly on a few at a time, pile on as much or as little chocolate as you would like.
Sprinkle on a little sea salt and top with another piece of toast.
Set them back on the warm cookie sheet while you make the rest to help melt the chocolate a bit more. If you want them melted even more, pop them back in the oven for a minute or two.
Notes
VariationsHazelnut spread - Switch out the dark chocolate for Nutella.Add fruit - Fresh berries pair well with chocolate, slice up some strawberries and add a few.Cheese - Brie or mascarpone cheese would add a savory touch and they taste great with chocolate.Keep an eye on the baguette during toasting. They will burn easily if you aren't careful.
