Don't forget something humans eat can be toxic to your dog.

Onions and garlic are other dangerous food ingredients that cause sickness in dogs, cats and also livestock. Onions and garlic contain the toxic ingredient thiosulphate. Onions are more of a danger.
Pets affected by onion toxicity will develop haemolytic anaemia, where the pet’s red blood cells burst while circulating in its body.
At first, pets affected by onion poisoning show gastroenteritis with vomiting and diarrhea. They will show no interest in food and will be dull and weak. The red pigment from the burst blood cells appears in an affected animal’s urine and it becomes breathless. The breathlessness occurs because the red blood cells that carry oxygen through the body are reduced in number.
The poisoning occurs a few days after the pet has eaten the onion. All forms of onion can be a problem including dehydrated onions, raw onions, cooked onions and table scraps containing cooked onions and/or garlic. Left over pizza, Chinese dishes and commercial baby food containing onion, sometimes fed as a supplement to young pets, can cause illness.
Be sure your not grilling any onions on the same grill your cooking the dogs meat.
A Word Of Advice About Trying New Foods
Before you introduce a new food to your dog, there's one other thing that you should take into consideration:
…the "begging" factor.
In our household, we've noticed that our dogs tend to "beg" for people foods any time they smell something they're familiar with. On the other hand, if they've never had it before, then they don't beg for it.
For that reason, we have only introduced 2 human food items to our dogs: peanut butter and bread. (And bread is only for very special occasions!)
To give you an example, any time we crack open a jar of peanut butter (...wait, I mean move the peanut butter jar from the pantry to the counter!) or open a loaf of bread, our dogs start salivating and licking their lips in anticipation of getting some. Yet we could hold a big 'ol steak in front of them, and they wouldn't blink an eye!
So just remember, once you introduce a particular food to your dog, there's no going back. They'll always want some of yours whenever you're eating it in the future.
When it comes to filling Kongs, we layer ingredients inside the Kong toy using various combinations of those two human foods and other dog foods, treats, and Kong-friendly products made specifically for dogs.
We've also reserved a handful of other human foods for times when our dogs have various ailments (like diarrhea) or need to take pills.
Those foods are: rice, cheddar cheese, cottage cheese, and plain yogurt.
