Yes - typical day - breakfast of beef sandwich and tea with semi skimmed milk - 600 cals.
Protein in the beef and milk, fibre in the bread if it was wholemeal
Coffee from machine - 40 cals so 640. Chocolate bar Dairy Milk - 250 - so now total of 890 cals.
Yes this is rubbish - lunch could have been better, and it would have been on the days OP got a package sandwich.
Packet salad from supermarket 300 cals for supper so now total 1190. Packet of pre packed fruit from supermarket 140 so now total of 1330
Salad and fruit - lot of goodness and fibre. Possibly excess sugar in the fruit, so could have been something with protein instead.
Overall - not too bad, could have been better but okay-ish.
