To give you an idea I have 1 or similar of the following each meal time
Breakfast eggs ( scrambled, poached, fried) with wholemeal toast, porridge with berries, weetabix, peanut butter on toast, full fat Greek yoghurt & fruit, at weekends pancakes.
Lunch salad with cheese/salmon/chicken. Sandwich. Omelette with mushrooms/cheese. Soup. Beans on toast. Avocado on toast.
Dinner anything really curry, Spag Bol, veg chilli with rice or broccoli rice, salmon with sweet potato and broccoli. risotto. Stir fry with lots of veg and chicken if I fancy. Chicken with asparagus and tarragon.
Snacks veg sticks (peppers, cucumber, carrot) with hummus. Popcorn. Any fruit I fancy. Home made flapjack. Chunk of cheese. Milky coffee
A milky drink ( I.e Latte) is fine as a snack, a latte for example made with whole milk has a fair amount of calories and does help fill me up.
And today I've had
Breakfast porridge ( made with whole milk) with blueberries & seeds
Mid morning Apple and carrot sticks with my babies
Lunch mushroom omelette, a couple of spoons of full fat Greek yogurt after.
Now I've got a milky coffee and 2 biscuits.
Dinner tonight is chick n and veg stir fry with noodles.
Dessert a couple of squares of dark chocolate and a black coffee
