Lotek is a traditional Indonesian salad that features a mix of blanched vegetables tossed in a rich, tangy and savory peanut sauce with a touch of sweetness and spice. It's similar to Gado Gado, but rather than serving the sauce separately, the peanut dressing and vegetables are mixed together for Lotek. Plus, it's usually a little tangier, making it a refreshing salad that is bursting with flavor.
