Looks pretty healthy :) But a little limiting.
I would recommend alternating and trying other seasonal veggies/fruits:
cauliflower, steamed or mashed like potatoes
red cabbage, added to salads
spinach, steamed, sauted, in a salad
other root veggies like rutabagas, parsnips, turnips can be added to mashed potatoes, try one at at time or google other recipes
sweet potatoes
frozen corn
tomatoes
My kids favorite daily snack is roasted seaweed, probably b/c it taste like a chip. It is available at Asian groceries and sometimes in your ethnic aisles. If you want to see vegetables that American's never buy and eat, go there. The Asians eat so many varieties of roots, and shoots, and radishes, and mushrooms and green leafy vegetables not ever available or recognizable in the standard American stores.
