Am I dieting correctly?

Really new to dieting and excercising, 5'10" height, weighed 230, lost 10 pounds to 220 since March 27th, I know I'm doing something right, but I want to make sure I'm not gonna start burning muscle instead of fat. Below is my basic foods I eat, and I eat 2-3 meals a day, plus 1-2 muscle milk protein shakes a day. Keep in mind, I'm going to give you meals that I eat, sometimes I eat the same things every day, sometimes I switch it up, but this is how my meals look.

For Breakfast:

2 boiled eggs and 1 peice of sugar free whole weat bread

or

1 egg fried in olive oil, turkey sausage, or turkey burger patty (if I don't have turkey bacon or sausage), half a peice of sugar free whole wheat bread, with turkey gravy

or

2 baked egg, backon, spinach muffins (sounds weird, back in muffin sheet, crack an egg, wrap a peice of bacon around it, and top it off with spinach and back 15-20 minutes, best with turkey bacon)

Snacks:

Fiber one Protein Bar, or Apple.

For Lunch and Dinner:

1-2 peices of grilled chicken with spinach and kale greens

or

1-2 peices of salmon, flounder, tilapia, or whiting with spinach and kale greens

sometimes a grilled chicken salad with no fat dressings, or tuna salad

I do fry the greens in olive oil so I still get some healthy fats in my diet, and the greens provide enough carbs I believe. I want to make sure that this is enough to prevent muscle burn, but help fat burn, I'm pretty much sticking to no sugar diet, as you can see. I also walk 3-5 miles a day with a 15 pound weight as of yesterday, sometimes give or take a mile depending on how the weather looks.
