I have a super easy cucumber salad receipe.
1 cucumber sliced fairly thin, 5-10 cherry tomatoes (depends on how much you like them, I find them easier to eat than regular tomatoes) 1 oz onion sliced very thin. Throw them in a bowl with a couple tbsp of low fat italian dressing. Super good. Especially if you give it a couple hours to marinate. I usually make it in the morning and have some for lunch.
You can always throw additional veggies in it too. Carrots are good in it, fresh green beans, snow peas, brocolli (try very small pieces).
Oh, and niapage, pototoes are perfectly healthy, especially with the skin as long as you don't smother it with butter and full fat sour cream and bacon and all that stuff.
Bep is completely right, you'll be surprised that once you start eating veggies prepared different ways you might actually like them. I made a spinach lasagna that several girls at work made a fuss about trying because they "hate" spinach. But once they tried it, they were arguing about who got the remaining portions of it. LOL
