What do vegetarians eat?

My sister-in-law decided to take up vegetarianism for one week and I decided to do this with her. I think I understand the concept of a vegetarian diet and I know what nutrients to focus on in order to avoid any malnutrition. After looking around at a lot of vegetarian recipes though, I find myself at a loss. Everything that I found sounds good if I want to go through the whole process of making it, but it seems rather tedious to follow only recipes. I wanted to get an idea of what vegetarians eat on a regular basis. On an AVERAGE day, what is it that you eat?

Breakfast (when I'm awake!) - Whole wheat toast, cup of green tea, coffee and soya milk

Lunch - normally grilled haloumi and a salad with LOTS of jhalapeno's and olives.

Snacks - Normally just a slice of bread and vegan butter

Dinner - Depending on my mood - homemade ravioli (veganised) or Vegan pitta pizza or veggie suhi. I love making small things and making a 'buffet' for the meat eaters and then relishing their faces when they find out they infact ate veggie food!

Oh, I could live on my home made pesto and warm bread!

Of late my diet has included far too much booze, which would explain my half a stone 'leap' in 2 weeks.. sigh..

note- I'm not vegan, I just tend to take only sheep milk..
