Some of Tom's favourites are pasta (this can be left overs from a previous meal), fried rice (leftovers again), baked beans, omelette (not microwaved but can be whipped up quickly when you get home and you can chuck some vegies in like tomato and capsicum), zucchini slice (baked ahead of time and then microwave to warm up), same for quiche or anything similar. Or sometimes when he gets home from day care tired I will just give him a yoghurt and banana for dinner - often he has a warm lunch at day care (could be anything from the above list), so he is not missing out on any nutrition. HTH.
