A Tasty Baguette Sandwich with Asiago Cheese, Arugula & Balsamic Onion Marmalade
This is a simple sandwich that relies on a few quality ingredients. This sandwich is all about the juxtaposition of flavors and textures – the sweet caramelized onions, the peppery arugula and the crunch of a perfectly baked baguette. This can be served as a hot sandwich by toasting the bread and letting the asiago melt and using warm freshly made balsamic onion marmalade or enjoy at room temperature.
You can purchase a pre-made balsamic onion marmalade, but it is super easy to do at home. It just requires a bit of patience waiting for the onions to caramelize. The recipe is below. Once in your pantry, you will find other delicious uses for the balsamic onion marmalade – a side to steaks, quiche or as an accompaniment to a fruit and cheese plate.
1 Baguette, Freshly baked and sliced in half lengthwise
1 c. Arugula, shaved or thinly sliced
1/2 c. Balsamic Onion Marmalade

Black Pepper, freshly ground
2/3 c. balsamic vinegar
