Welcome to YT!
It's great that you're feeding Tink some extra veggies-I bet she loves them, and they're great for her in moderation. My dogs like zucchini, carrots, peas, green peppers, spinach, lettuce, and lots of others too. Just remember that onions & garlic, among other things are NOT good for our yorkies, and can make them very ill.
Scrambled eggs are wonderful for them too-just remember no salt or seasoning on them. My two like their eggs with a little shredded cheddar, or a little cottage cheese on top.
Twice a day feedings sound great-I feed my two twice daily too. For smaller/younger dogs, sometimes 3-5x daily is what they need. Since your Tink is already 5 lbs, she is probably out of the woods where you'd need to watch her for hypoglycemic episodes.
