Normal day for me:
Breakfast: toast or a bowl of cereal (recently a toasted hot cross bun)
Lunch: a sandwich or salad, usually Ham, lettuce, tomato, cucumber, pepper with salad cream or mayo.
Dinner: Chili, curry, pasta bake, casserole, stir fry, with lots of veg ie something homemade and easy to stick in the slow cooker or Chuck together when DH finishes work (usually late!)
Snacks: Apple, a few biscuits, a packet of crisps. depending on how hungry I am and what I've been doing.
Some days I skip breakfast or lunch as I'm just not hungry but I drink tea and water all day so tend to fill up on liquids. I don't think I ever have an empty cup or glass for more than half an hour!
DH is generally quite picky with his dinner accompliments so he will usually have chips and I'll have jacket potato or similar as I hate oven chips with a vengeance!
Portion size is an issue though as it is for most. What you class as a normal meal may be a snack for some or a feast for others. I use standard sized dinner plates for an evening meal with a pattern around the edge and make sure my dinner is always only in the non patterned section of my plate so I can control my portion sizes as I'm more likely to over eat in the evenings.
