My son loved (still does) peas. I just pop a few in the microwave in a bowl of water, right out of the freezer bag. Then they can be refrigerated and eaten cold. Also, frozen fruit works great for babies because they tend to be softer once defrosted. I will take a few pieces out of bags of frozen fruit, cut them smaller while still frozen, defrost in the fridge and they are perfect. Mango works really well and was my son's favorite at that age. The other fruits and veggies you've had suggested are great. For apples at that age I would cut fresh apples up into small pieces and freeze them and do them the same as other fruit. They are really soft when defrosted. Yogurt is also great and healthy- protein, dairy, fruit all in one. I buy plain whole milk yogurt and add fresh or frozen fruit to it myself, no added sugar that way. Funny, I use kitchen scissors too, they are so much easier than chopping. I had to go buy a second pair to be able to use them twice a day.
For babies under one, it is just about trying new things, their primary and even total nutrition needs are met through breastmilk or formula. So don't worry about her 3 course meals yet. And for later, just so you don't get in a panic about whether she is getting the variety she needs, keep in mind that baby's nutrition intake is measured in terms of a full week, not a day. So if you were to take her into a doctor for some nutrition-related concern, they are going to ask you to keep a journal of what she eats all week. As long as all the requirements are met in a week, it doesn't matter if she will only eat grilled cheese one day and only eats applesauce the next. I try to balance things daily, but that is mostly to be able to keep track better, and also to keep mine regular. (Applesauce only for days will not make for a happy tummy.)
Here is a great website that has healthy balanced meals, and a lot of them are daycare lunchbox style. If you are on facebook, you can subscribe to her page and get daily meals in your newsfeed. It is a homemade baby food blog, basically. www.weelicious.com
Hope that helps!
