The weather man willing, Lower Mainland barbies get their first airing this long weekend. But plain old burgers and steaks are so last summer. Before you fire up the burners, invest in Matt Dunigan (the former quarterback) and Chris Knight’s Road Grill (McArthur and Company, $29.95). Recipes for lamb sliders, citrus-tea-rubbed halibut with orzo-fennel-orange salad, planked apricot Dijon pork, plus sides and marinades galore prove these guys aren’t just blowing smoke. Their same-name TV series debuts Monday (May 19) on the Food Network.
