I love the bags of frozen vegetables in variety packs like california blend, tuscan blend, stir fry blend, southwestern blend, etc. <5 minutes in the microwave and toss with some whole grain pasta, maybe some bites of meat saved from dinner. This can be prepared the night before. Warm or cold, my daughter always eats it up, it's finger friendly and healthy in less than 10 minutes.
I think the key to her eating the veggies is the variety packs. It's easy to refuse a pile of broccoli, but with the variety, she feels empowered by having a choice of which veggies to eat (win for her) and because she always chooses to eat at least some of them (and often all of them) there's no battle (win for me). And it's so easy there's no excuse to not offer some veggies with each meal.
If I'm really in a pinch I'll open a can of soup with the same basic ingredients, vegetables, meat, noodles or rice, and just drain off the broth so it's not so messy for her to feed herself.
My daughter's also a fan of the deconstructed sandwhich. If I'm making one for me in the morning I just take the same items (bread, cheese, avocado, lettuce, tomato, meat, etc.) and cut them into bite sized pieces for her.
Also quick and easy is a scrambbled egg that you can punch up by mixing in a pinch of chopped frozen spinich (it thaws as the eggs cooks). Top with a little cheese and some diced tomato and avocado. My daughter doesn't mind cold eggs, so it works as a meal prepered ahead of time.
