Good dinner for weight loss

Hello,
I am at that point in my weight loss journey where I only need to lose about 10 or 15 more pounds to get the body i want (I just got that stupid little pooch hanging on my lower abdomen and have lost about 80 lbs so far) any way I just started meal prepping a few weeks ago, which has really helped me to keep track of my calories and macros. I really like to mix it up, but this last week I made veggie stir fries everyday (with a protein like tuna/salmon/shrimp/chicken) and I could honestly eat that for dinner everyday. I use a small amount of coconut oil, lots of veggies and 1 serving size portion of protein with a tbsp of low sodium soy sauce and a bit sriracha. But what I am wondering is, is stir fry even healthy? The way I make it, it comes out to about 230 calories (more if i use chicken). Should i continue with the stir fry everyday or should i find a healthier alternative (or is stir fry actually that healthy?)

Also if anyone has any insight/tips/advice on how to finally get rid of that last bit of fat I would be forever greatful!!! I try to stick to about 1200-1300 calories everyday and I do weightlifting and cardio (about 15 to 20 min on stairstepper/treadmill/eliptical)

And one more question for those of you who are in a similar boat, I have two days for training legs, but if I want to actually build muscle on my lower body should I eat more calories on leg day or will that just hamper my weight-loss efforts (aka, will i still be able to lose fat even though I am eating a surplus of calories on leg day?)
