Cook broccoli for 30 seconds to lightly char in a couple places.
Reduce to med and add corn. Cook further 2 minutes until there is some colour on the kernels and it is a bit soft. Remove from heat and cool to room temperature.
Toss corn and broccoli with remaining ingredients, adding cayenne and ground pepper to taste. Squeeze lime juice over it just before serving.
Notes
*Poblanos would also work here for those that like a bit more spice
