Go easy on the processed meats like hot dogs and bologna as many of them contain fillers and sugar and the sausage and bacon because of the high salt content unless you don't have problems with water retention.

Unless you dislike them, you can also have beef, pork and fish (in addition to tuna).
Some additional veggies to add for variety might be zucchini, green beans, cauliflower, broccoli, radishes and romaine lettuce and don't forget that you can have olives and avocados (if you happen to like them) in addition to your veggies during induction.

If your choices sound as though you may get bored quickly, check out the recipe forum for some ideas on creative things you can do with all the fresh meat and produce you're about to purchase.
