Looks good. I love my Grill Grates on a Weber Genesis.
In the summer, we often make fajitas by doing something similar to your cook. Sous vide chicken breasts (145 for 2 to 2.5 hrs), then finish on grill for a couple minutes to brown. Use the flat side of Grill Grates to cook up a pile of sliced onion, bell peppers, and jalapenos. Make Tortilla Land tortillas on the grill (one minute per side on lowest heat). Choose from cilantro, squeeze of lime, sour cream, cheese, and salsa for toppings.
We usually make a bunch of the meat and veg, and eat the leftovers with fresh-cooked tortillas during the week.
