/ck/ - Food & Cooking

/fit/ here, I want to know If the talented and experienced anons on /ck/ can improve on my diet.

Requirements:
Must be cheap as fuck I'm an ascetic and work as little as possible. Can't cost any more than 150% of my current diet
Must be at least not disgusting
Must take little time to prepare (see current diet)
Preferably vegetarian
Must contain at least 130g protein and 3000 calories
Foods have to be available in bongistan

Here is what my current daily diet looks like:
1.5 litres of semi skimmed milk - 50g protein, 800 calories 75p
200g of sunflower seeds or peanuts - 45g protein, 1200 calories, 55p
400g of fresh white bread with butter or soup- 40g protein, 1000 calories, 70p (or sometimes a supermarket three cheese pizza with similar stats)
Totalling 135g protein, 3000 calories, £2 per day

Can any of you think of any way to improve on this?
