I am a keen cook, have even done it professionally, but when I feel poorly (like today) my “go to” is warm toast with peanut butter.
Or tinned tomato soup (Heinz de préférence)
If I have the energy, (which I don’t) my final favourite is thick sliced ham, fried egg and (oven) chips.
Please hold my dear GD in your heart for a few days.

, I'd forgotten about that!
