Recipes rich in protein for toddlers

[Sarajessgirl]

My ds, 2.5 years old, had some weight loss recently(she is a fussy eater). It would be great if you can share some recipes that would help her gain weight; ideally some protein rich ones.

Anything with nut butters. Sandwiches, Apple to dip into almond butter, peanut butter stirred through rice pudding.

What does she like to eat?
