I'm with SuzzyQ .... same thing when my husband was sick and then died, it was nice to receive the desserts/sweets as a treat, but we more-so welcomed the main course foods as they were more satisfying. He was a meat and potatoes type of person, and continued to enjoy them until close to the end.
Speak with your friend and ask her what she would like you to bring.
There could be restrictions as to what he can or cannot eat.
And perhaps you already know the answers.
Plus remember his wife, there might be a food that she would really enjoy
that she would not have the time or energy to prepare herself.
One of the things I appreciated the most was when someone would say,
we're bringing supper for you tonight. What time should we come?
They would arrive, with food straight from their oven and ready to serve.
They'd often set the table, and leave everything ready, even setting the table
....... and then leave!!!
Sometimes it was just nice to be left on our own to enjoy that meal,
without the commotion that others can create.
