While that turkey dinner is roasting for Thanksgiving you have the opportunity to start impressing your guests with some tasty snacks and appetizers and you really can't go wrong with these roasted brussels sprouts and halloumi sliders! The idea is to start with some large brussels sprout, cut them in half and roast them, which really brings out their flavour, and then to skewer them up on toothpicks along with some tasty fillings and then serve them up as finger food! These little roasted brussels sprout sliders are one of my favourite fall appetizers and a great way to fill the is with some fried halloumi cheese, sweet caramelized onions and some tangy grainy mustard! Halloumi is a cheese that retains it's shape when fried it's so amazingly good when fried in a bit of butter until it's nice and golden brown and crispy on the sides and warm in the centre and finishing it off with a splash of fresh citrusy lemon juice is just heavenly! The combination of roasted brussels sprouts, fried cheese, sweet caramelized onions and grainy mustard in these sliders will ensure that they disappear quickly and they may just outshine your Thanksgiving dinner!
