In Season Now … Asian-Style Burger with Sweet Potato Crisps

My family loves a good burger meal. We don’t often have them but when we want burgers, I make them at home. Burgers with the works. We like the idea of assembling the burgers, anything goes sometimes, depending on how simple or how gourmet you want yours to be. This recipe is for an Asian-style one. Very distinct flavours of lemongrass, lime, coconut cream and a bit of chilli. Chilli is optional of course, if you do not like spicy foods. So, I will let you decide on how much chilli flakes you want to use or maybe not add chilli at all. Coconut with crunchy peanut butter sauce makes these burgers quite authentic Asian. Serve them with deep fried sweet potato crisps. Yes, deep-fried. You can bake them of course if you want a healthier option but I’m sticking to this method of deep-frying thin strips of sweet potatoes. Trust me, you will want them deep-fried. I had to stop myself from eating the crisps every time I scoop them out of the pan. Otherwise, there will be only burgers to serve!
