Hi Donna. If you check this link (scroll to the bottom), there's a whole whack of low GI vegetables. (Btw, I'm not endorsing that product, it just happens to be the first lengthy GI list I came across.)

There's a fruit list there, too. Don't fall into the trap of thinking you must have sweet fruit - tomatoes, zucchini, eggplant, cucumbers, squash and peppers are all fruit and have similar nutrition profiles to sweet fruit, without the sugar.
