DH sauteed roasted corn with vidalia onion and a little tomato -- only complaint: he should have made more to use for leftovers in turkey tacos. (Thanks to the DCUM poster who suggested this on a thread I started asking for corn suggestions.)
DS roasted brussel sprouts, which I love, and then, per his girlfriend's suggestion, added just a touch of smoky paprika at the end. Delicious --and he made the two most important women in his life happy!
DD made America's Test Kitchen mashed potatoes -- her first batch was a greasy mess and had to be thrown out, but the second round -- with garlic and chives was iconic -- not even a spoonful left! (Plus, a bonus teachable moment on not freaking out when little things go wrong.)
Pan-roasted corn suggester here. Thanks for your return suggestions! These sound awesome. (DS thinks tacos are the greatest food ever. Don't know why we never thought of this.)
