mythik, rereading your posts... maybe you can try to include more veggies in breakfast and lunch, and let dinner be "snacky" if that is a tough time of day for you? Or just make sure to have pre-washed veggies/salad around so you can throw a side of veggies on your plate with very little effort? You can also grate (or thinly slice/chop) some veggies into sauce when you are heating that up for pasta. Or even just some frozen veggies- don't knock them. They are easy and very nutritious. Make a big tasty salady lunch for yourself the night before, and don't stress if you can't manage it at the mad-after-work-before-bed rush time. For the first trimester I felt NASTY at dinnertime and was hardly eating anything. Then I'd want ice cream at like 9PM. So I made sure to have a really good healthy breakfast and lunch, when I was hungry.
Make aheads are a good idea, so they are on hand and easy to eat. Very nice kale salad: wash and finely chop kale, mix with lemon, olive oil, salt, and massage together. Add some chopped raisins and some optional seeds (help, sunflower, etc). Let it sit at least a few hours- very good the next day or two. That is easy peasy to make, keeps a couple of days, and it nice as a lunch, or stuffed into pita with cheese or hummos for lunch. Another I make: Quinoa and beans, some minced scallions and/or red onions, very thinly sliced veg (whatever you have... peppers, cabbage, tomatoes, carrots, raw or cooked greens, etc), minced herbs like parsley or cilantro, and dress with some vinegar, oil, salt. Also keeps and travels well. I just made a lentil salad with lentils, red onion, cabbage (minced), olive oil, salt, cider vinegar, and a handful of dried cranberries and some shaved and chopped parmesan. If you intentionally make extra cooked greens at dinnertime or whever, you can chop and add into a really quick breafast omlette.
