I put the potatoes on to steam and when they were half done (ten minutes) John lit the grill. The potatoes were finished by the time the grill was hot. While John cooked the shrimp, I took the potatoes off the heat and then used the same pan to cook the broccoli. I cut open the potatoes and plated them along with the broccoli and shrimp. A healthy squeeze of lemon went over everything. Lemon juice is surprisingly good on potatoes! This was definitely a half an hour meal from beginning to end.
