Do you have a microwave? I had my whole range go down eight days from port one time. Thank goodness, only had twelve people on board to feed, but they were soup lovers.
I did the saute veggies and herb thing in the microwave, then added meat? or grains? or beans? and some stock and put in crock pot to finish.
BTW, most know that fish, chicken and veggies work well in microwave, but meatloaf comes out really nice, like a big juicy meatball, need sauce, not brown. Also frittatas and bread pudding for breakfast; and, of course oatmeal. you learn a lot in eight days, did have commercial size microwave and a great micro cookbook
