Yes, you can eat as much vegetable as you like from this list:-
Green bell peppers
Olives (these should not be packed in distilled white vinegar)
Rutabaga (an excellent and strong antifungal food)
Sauerkraut (without vinegar, fermented only)
Seaweed (Rich in iodine & other nutrients)
Eat as big a selection at each meal as you can, 4 or 5 different vegetables. Eat them different ways – raw, boiled, steamed, sauteed, baked. This will make it more interesting and you will feel less hungry.
Just eating salad & onions all the time with become very boring.
