I cook a LOT and entertain a lot. Large groups of people too. I could become a caterer if I wanted.
I use every burner I have (4), my oven, my microwave, crockpots, outdoors grill and my patio bayou burner - year long.
DH asked me if I needed a kitchen remodel and I declined. I have a sunny and bright kitchen and medium expensive tools and appliances. I think it is more important that I am comfortable in my kitchen and that I am actually doing the cooking - making hearty meals and trying out new recipes and entertaining, instead of having a high-end kitchen and fixing just a meager sandwich for my family and not entertaining. What is the point?
