I think all kids go through a picky phase several times before they hit six. I know all of mine did.
To be honest, your daughter is eating fairly well. She has a majority of food groups and is eating ideal foods.
Try adding applesauce or bananas to her pancakes, or make pancakes out of different things such as cornmeal (with shredded cheese in it and real corn) or whole wheat flour (with oatmeal and shredded sweet potatoes, carrots, or zuchinni). Stuff her french toast with low-fat cream cheese and try applesauce or yougurt on top of it instead of syrups. With her hotdogs, try making homemade catsup out of fresh tomatoes, a little salt, and sugar. Be certain you are buying hotdogs that are lower in fat or preservatives (I love kosher ones for my kids meals). If she likes fries, make oven fries with both sweet potatoes and regular white potatoes. Make cereal clusters with dried fruit and marshmallows (like rice crispy treats).
And best of all--- take her shopping with her own shopping list and cart. When my kids hit the 4y/o pickiness, I took my digital camera, made photos of common ingredients they could help find (ie: apples-green and red, lemons, oranges, bananas, breakfast cereals that were whole grain no sugar added, etc...) and put it together with a little ring binder in the corner. I gave them a mini shopping cart from the Dollar General and let them loose with me following carefully behind them. By letting them pick out the fruit and snacks themselves, they wanted to eat it because it was "theirs". I even let them help me cook it. For green eggs and ham, we blended spinach with eggs and then scrambled it. Served it with ham and toast with ripe avocado sliced on it.
My kid will eat almost anything now--- but love helping me decide what they have to eat.
