Thanks @Huggybear16 
I'd already got a few things like extra hot chocolate, custard powder, shit loads of tea and lentils but today have bought:
Frozen broccoli
Frozen peas
Frozen spinach
Frozen seeetcorn
Tinned pineapple
Tinned mango
Tinned cherries
Coconut milk
Big bag of rice
Big pack of spaghetti
Bag of macaroni
Bag of penne
Tofu (can be frozen)
Butter (also to freeze)
Long life milk (semi and skimmed)
Big bag of sugar
Bagels for the freezer
Porridge oats
Freezer bags
Bread (one white, one multigrain/seed) for the freezer
Chopped tomatoes x4
Garlic paste
I also bought bagels for eating now, fresh veg for making soup (had for dinner and the rest I will freeze), crisps, jam, hot cross buns, soap, kitchen towel.
I spent just over my budget but feel happy that my freezer is pretty full now as had stuff in already, and my cupboard (I only have one good cupboard as it's a small kitchen of a shit design) is full of ingredients to make things.
I have a fussy eater but hoping by engaging her in cooking she'll eat more variety. First stop is making lentil dahl. The oldest and youngest will try anything. Middle Miss is a pita when it comes to new food but I've told her brexit might mean less choices and she really does have to eat what she's given now
