["My wife's cooking is amazing these days. She has really come a long way from when we first met.", "That's wonderful!  It's a lot of work learning to cook.", 'I can only grill food on a barbecue pit. She has learned how to create new dishes I have never even thought possible.']
Grilling is a skill too!  Sounds like she is really enjoying cooking.  It's really an artform
My wife has really stepped up her cooking lately. I'm eating so healthy these days and the weight keeps dropping!
