I cook for 2 but this could be stretched to feed 3 with a salad, light soup or some fresh bread.
I used leftover chicken but you could use 1 chicken breast, cut into small pieces and quickly fried.
You could substitute 3oz (90gr) fresh spinach, chopped, for the thawed spinach. Just stir it into the ricotta.
