We've done a lot of dipping - steamed broccoli in uncheez sauce, for example, or lightly breaded zucchini in marinara sauce.
Also, my 2yo is a soup fiend. I can pulverize just about anything into a pureed soup and she'll eat it. Do a search in this forum for "chickpea soup" and you'll find my recipe. I've added pureed spinach to it, pureed carrots, etc.
Another thing you could do is just keep offering and wait it out. My 5yo is pickier about veggies now than she was at 2, but she still eats broccoli, carrots, potatoes, celery, peas, green beans, some squash, and edamame, and I didn't change our approach or her diet at all. Sometimes kids just don't like something until they suddenly do -- or, in our case with DD1, vice versa!
