grilled chicken with dijon and lemon

how's this for a summer recipe. i have to admit my husband did the grilling, but i swear i did everything else!

grilled chicken with dijon and lemon

4 bone-in, skin-on chicken breasts
1 cup dijon mustard
2 lemons (both lemons zested and only 1 juiced)
1 tsp red pepper flakes
sea salt

1. prepare marinade by putting mustard in shallow bowl. zest 2 lemons adding the yumminess to the bowl. juice only 1 lemon into the bowl. add red pepper flakes.
2. paint mixture on chicken breasts and allow to marinate at room temp for 2 hours.
3. sprinkle sea salt on top of chicken and grill breasts at 375 degrees for 12-15 minutes on each side. you want to get the skin crispy so allow the time to do so.
