For me it depends on the time of year and the occasion. Today we have having Prime Rib for Mother's Day.
My son and I love lamb and during the summer we will BBQ lamb fairly often.
If we are going out, which I do appreciate, I love to go to our local wine bar for Tapas. Small plates of interesting food that I would never make at home. On a similar note, Dim Sum is fun and a great way to sample different foods.
My sil and brother's family love my lasagne. I house sit for them one week each summer and always leave a lasagne in the fridge for them. They can either cook it when they get home or freeze it for a later meal. My sil works hard as a physician and I like to leave the house a bit tidier than when they left and some food in the freezer too. Last year I house sat right before school started. I baked 3 doz banana choc chip muffins and froze them for school lunches.
