It's a perfectly reasonable selection of food. Could do:
Cheese sandwich (2 rolls), cherry tomatoes, & cucumber sticks on 3 days.
Baked potato with 1/2 tin baked beans on 2 days
Boiled egg, cucumber slices, fruit & yogurt for snacks /pudding.
Keep the sweetcorn in your cupboard.
Or
Omelette, bread & butter, cherry tomatoes, sweetcorn. 3 days.
Oven baked cheesey wedges, baked beans. 2 days.
Fruit & yoghurt for pudding. Cucumber & cheese for snacks.
Or
Toasted roll, baked beans & scrambled eggs. 2 days.
Cheese, tomato & sweetcorn topped toasted rolls, cucumber sticks. 2 days.
Baked potato with cheese. Tomato & cucumber slices.
Fruit, yoghurt, cucumber & tomatoes as snacks. Also 2 rolls & 2 leftover eggs, hardboiled.
1 leftover potato.
I'm not sure if the OP has any experience of receiving food from the food bank. But obviously they would "get more" there, a food bank parcel is designed to feed a family for at least a few days. Not one child for one week's worth of lunches. And, having received a food bank parcel, I can tell you I'd sooner have the fresh food for making lunches. Food bank parcels are often almost entirely tinned food, or things like plain spaghetti, because it keeps well & is quick to cook.
I'm also interested in the OP's perceptions of receiving a foodbank parcel. Would that also be "Dickensian" and embarrassing?
