When proposing alternative meal options to your principle, it a good idea to estimate the avg cost for making each item (we all know schools are cheap in this area... well most anyways) if you show them just how inexpensive it can be then chances are you will get what you want... vegan options

Below is a list of very cheap, easy to make and very popular even among omni's:
- corn jacks
- hot dogs
- vegan spring rolls
- sausage rolls
- tempeh Skewers
- pizza slices / pizza pockets
- salad (fruit, garden and even pasta salads)
- vegan lasagne (or even eggplant lasagne yum)
- eggless quiche
- veggie pies/ pasties
- toasted and fresh sandwiches
- vegetable soups
- potato jacks
- baked quoina bites
- ravioli
- sushi
- burger patties
- taquitos
- vegan pastas and pasta bakes
- vegan risotto
- veggie filled oven bake or grilled bell peppers
- vegan pancakes / pikelets
- vegan chips / wedges / Gems (cooked in olive oil / peanut oil is best)
- awesome gravy recipe – is just caramelized finely chopped onions (sometime I like to add mushrooms too) + freedom food vegi spread and a couple pinches of flour (basic but sooo yum)
- dont forget vegan chocolates / cakes / cookies / ice cream and smoothies
