Sometimes it’s a challenge to come up with a satisfying, filling meal that’s also cooling in summer. Sure, all those leafy salads and gazpachos are great, but sometimes they leave you hungering for a mid-afternoon snack only a couple hours later. Solution: Causa. This layered Peruvian dish uses cold mashed potates as a base, with chicken (you can also use fish), loads of lime and fresh herbs, plus slices of avocado. We added some smoky roasted pimento on top plus some pickled red onion.
