filling food for toddler!

my little one likes to EAT! he is 15 months old, today! and still nursing at naps and night time, which is what i’m trying to stop.. he does eat 3 meals and a few snacks a day whenever he tries to have breastmilk i just give him a snack. but he’s still demanding the breastmilk at sleep time. someone suggested maybe trying more filling foods. So what are y’all’s breakfast, lunch and snack recipes for your kids that fill them up! Planning to make egg bites, oatmeal, maybe turkey roll ups cheese cubes and veggie straws, yogurt/smoothies, fresh fruit, all from recommendations from a friend but i would like to get a lot of options so we can see what he likes and also what works to keep him not hungry! thank you 💙
