Is this a good/healthy diet?

I'm trying to be healthy. It's been a struggle, but I think I nailed it. I just kind of want your opinions, and maybe any advice you can give to make it better.

Breakfast: oatmeal and a fruit/yogurt (normally I just eat a banana though)

Lunch: Meat, rice and beans (or chili, soup, fish etc with lots of green like salad or broccoli)

Supper: Whatever the family has, unless it's fried. Then I make fish with a veggie medly with a piece of fruit and maybe a dinner roll.

Snacks: I can have one sweet snack, like a cookie or brownie, and then normally I eat almonds, a spoonfull of peanut butter, or an apple or banana.

I've cut out processed foods, overly sugary stuff. I don't drink soda or juice. I make everything I eat (well, with the exception of the peanut butter). All I drink is tea, coffee and water.

So what do you think?
