Avacados always work well, little salt and pepper makes a good snack. I am also a big fan of cheese and fruit, particularly berries and whole milk riscotta or cottage cheese. You could always cook extra bacon and eat some for lunch and some for breakfast. Get used to cooking bigger meals and saving the extras in tuperware for later meals. Also I am fond of eating few bigger meals and going longer with out eating, today I had a huge breakfast around 8 and wont eat again till around 5. Good luck.
