I've gotten so, so lazy

I'm eating quick convenience foods and it's making me so sluggish! I'm maintaining weight some how, but I really don't know how!
Today's been a somewhat good day I've had:
B: apple and a mouthful of a prune

S: mini egg fondant cake thing
L: 2 slices tiger bread with butter
S: mini egg cake thing
D: roasted parsnip/carrot/sprouts/pepper/sweet potato
S: chocolate cake
So lots of crap, but mixed in with good stuff, but a normal day woul be White toast for breakfast (an improvement on nothig), either something picky for lunch, or a pasty from greggs if I'm at work (accompanied by a chocolate bar and/or bag of crisps) and dinner is usually some kind of bean grill out the freezer with chips
I'm completely out of ideas what to have, especially for lynch and breakfast. And I'm lazy too which isn't a good combination with school holidays! And I don't eat meat/fish/eggs unless eggs are in something (like cake

ooo: ) so your typical healthy eating plans online just don't work for me!
Help!!!
