I'm on a diet. Was my dinner good?

I'm 16. For dinner I had half a sandwich using 100% whole wheat bread and 1 slice of turkey with a little spray of olive oil on the bread and I had a medium size salad with a few pieces of baked/broiled fish and a dressing I made using extra virgin olive oil, spicy brown mustard, honey, and cajun seasoning. Was this good cause earlier for lunch I had a little mashed potatoes (about a serving), broccoli, and 2 pieces of baked/broiled fish?
