Lamb burgers with mint pesto and whipped feta

Pesto Italian cuisine

This is my attempt to recreate a rather fabulous burger I had in Hawkes Bay, New Zealand. It's a bit involved, with two different condiments made from scratch, but everything can be done in a food processor and made ahead of time. This will make more pesto and whipped feta than you need for the burgers--use the leftover pesto on pasta or grilled meat, and the whipped feta as a dip with veggies. And to really take these burgers over the top, serve them on pumpkin buns: https://food52.com/recipes/28232-pumpkin-burger-buns?preview=true
