When I worked late a couple of days a week hubby cooked and I got so fed up of beige food I ordered one of the food boxes , all ingredients pre measured , it was a godsend , we all picked meals and some weeks we couldn’t find anything we thought we would like so picked different things , we were so surprised that we liked dishes we would never normally have tried , plus a lot of them were 10 minute meals or at most half hour , I only stopped them recently as they cater for 2 or 4 and I was buying extra ingredient to cater for our 5. Could be an option for you to try different things and also have a quick meal option . We are so completely different as I love eating as my waistline will testify , I get so much enjoyment out of cooking too. Can you try making something for you all that you like and not mention it and just see if she eats it ? Appreciate it is tricky and you don’t want to rock the boat at all.
