Although the weather is cooling summer is not quite over yet and I wanted to send it off with a bang with these summery caprese BLT balsamic roasted portobello mushrooms! One of my favourite things in summer is the fresh field ripened tomatoes and I always enjoy them in BLTs! I was thinking about taking this idea and combining them with another favourite food, mushrooms, and so the idea of a portobello mushroom BLT got stuck in my head. The basic idea was a BLT with roasted portobello mushrooms as the bread and either using a second mushroom cap to make a sandwich or just using one and going with an open-faced sandwich. Instead of going with a plain portobello mushroom I decided to add some flavour by marinating the mushrooms in a tasty balsamic vinaigrette before roasting (or grilling) them until tender. Next up was some bacon, basil leaves (as the lettuce) and tomato to give one amazing portobello BLT but I could not help but keep going by adding some summery fresh basil pesto! That got me thinking about a caprese salad so I added some mozzarella and a balsamic drizzle taking this mushroom sandwich way over the top! These caprese BLT balsamic roasted portobello mushrooms are just packed with flavour and they are a great way to celebrate the end of summer!
