What a thoughtful lady you are! I'm sure she appreciates your efforts to help her.
I often brown a lb of hambuger, drain the fat, and add a jar of Ragu. I boil 2 cups of wide noodles, then mix the two together. This plus a green salad makes two meals for my husband and me, 4 meals for her. A bread roll and some parmesan cheese is nice too. I find that it freezes very well. You could make a batch, divide it into 4 meals, give her two and freeze two for later.
