My 17mo adores bananas, apples (even before he got all his teeth, he would suck on apples), string cheese (full of protein which is good for cranky babies), Mini-nilla Wafers, Graham cracker sticks, dry cereal, Gerber Fruit juice snacks, Gerber Crunchies (loves these in zesty tomato and won't touch the other flavors), Quaker Chewey bars (can be chewed up even by two teeth with a little determination), sliced hot dogs (only at home), Lunchables, Jr. (has crackers, diced lunch meat and cheese), etc... Just walk through the grocery store ailes and see what you can find that seems appropriate. Use your imagination.
