Help with food for a bottomless pit

[upupallnight]

DS is 13 and seems to graze constantly. He races through all the yoghurts, cereal, bsbybels, boiled eggs. Tonight he had dinner (risotto) then fried eggs on toast not that long after. He doesn't eat massive portions at meal times as he doesn't usually want to though sometimes he'll have seconds etc hence me seeing him as a grazer. He makes himself banana milkshakes (with fruit, now powder).

He's slender and very active so he seems to need all the food he's eating!

What is the easiest and most cost effective yet still relatively healthy way of keeping him full??

• Make enough for seconds and thirds and he can just have multiple mini meals.
• Make massive salads (the MN standard) with lots of protein and fat - nuts, cheese, cured meats, olives.
• Fruit bowl full of cheap seasonal fruit.
• Buy blocks of cheese, not Babybels, and loaves of bread. Let him make himself toasties.

I make a big family sized bowl of pasta with sauce, sweetcorn, chicken and whatever else I can put in, for the fridge. Mine have this cold or heated up with some grated cheese.

It's a lot cheaper than general fridge grazing.

Noodles, the cheapest packet type, Dd used to text me from her room most nights asking me to make her some!

Other than than, oats are quite filling so porridge or flapjack, cheese on toast, popcorn is cheap if you buy it unpopped and make it in the microwave, add whatever, I'm a fan of butter and hot sauce.
Nut butters are good, on toast/pancakes/apples, frittata cut into wedges will keep in the fridge for a few days.

We had similar problems with DS at that age. Another MNer recommended this guide from the Caroline Walker Trust and with a tips from that DS actually smacked less and was eating much better.

I've just started a similar thread.

I actually have concerns about my ds eating habits. He's 15, also very slender lower end bmi so obviously needs the food, but he eats and eats and eats. All rubbish if he can get his hands on it.

Need to somehow get him to fill up on proper food.
