I eat a lot of veggies, but don't know that I have any special recipes...
One thing that is really yummy and low cal / low carb is to bowl some cauliflower (either frozen or fresh) and then mash it up, but some salt, a little butter maybe some milk and garlic, etc... mock mashed potatoes! I didn't even think I liked cauliflower, but this is good and easy.
We eat green beans a lot. I don't get tired of them really... I like canned ones and you could eat a whole can if you wanted and it's only about 80 calories.
Also it's good and low cal to take a jar of unsweetened apple sauce and add some artificial sweetner (Splenda / Equal) and cinnamon, and a dash of salt.
Frozen chopped broccoli is handy, too, to add to lots of kinds of casseroles or probably even like mac and cheese, to kind of "stretch" the amount you can eat for the number of calories you want to have.
Tomatoes are so good, too, especially a little later in the summer... just on the side with a little salt.
Marinated cucumbers have nearly no calories if you make them with artificial sweetener... just peel and slice the cucumbers, and to taste make a mixture of vinegar, water, and sweetener. You can (or at least I do) re-use the marinade a few+ times, just maybe perk it up with a little more vinegar and sweetener.
Another favorite of mine, no recipe required (LOL!) is just frozen mixed veggies... they are economical and I think more nutrition than most fresh veggies in the store (which have been in transit so long, vs. frozen quickly). Just put a little salt water in a pan and the amount of veggies you want, bring the water to a boil, reduce heat and let it simmer for 5mins or so.
For me, I love having like a variety of things to eat on my plate, and I just try to eat mostly veggies, and then the "main dish" in a smaller amount. Now I crave veggies, which did not used to be the case. We're also going to put in a veggie garden which we never have done before and that will make it more fun, I think, to make and eat the veggies.
