Vegetarian here but Generally…
breakfast - scrambled egg with rocket or wilted spinach(microwaved to wilt), topped with tomato and a little feta or mozzarella
lunch - either left overs from the night before or home prepped cous cous grains with a bunch of veg (depends on what I have but often roasted squash/beetroot then a load of salad type things such as cucumber, peppers, tomatoes etc) with some cubed cheddar or feta, sometimes a few seeds and salad leaves
winter it is more likely to be home made soup for lunch - veg soup that has been slightly mashed with a potato masher but not pulverised so it’s fully liquid. I find the chunkier the soup the more filling it is
dinner - so many different things but maybe veggie spag Bol, maybe jacket potato, maybe home made curry, stew, etc whatever it is, the majority of the plate is filled with salad/high vitamin veg. So yes, a potato is a vegetable but I would have a smaller amount of that than the higher vitamin veg.
snacks - usually one around 10:00/11:00 as I have breakfast very early and will be one of something like apple, banana, 1X ginger biscuit. Just something small to see me through to lunch.
after dinner I often have 2 squares of dark chocolate.
i think the main theme with what I eat (other than it being vegetarian) is that the majority of what is on my plate is fruit/veg/salad and I make sure I eat big portions at mealtimes so I don’t feel the need to snack on junk food.
