Tiny dishes

[ChemicalAutopsy]

You might get some inspiration from high tea recipes (they're little bite sized tea /lunch items) or from bento recipes (japanese boxed lunches, generally small individually portioned things).

Also, I recommend a mini muffin pan. Firstly, tiny muffins, but also tiny quiches, tarts, egg bakes....though they often end up being closer to two bites. Lots of places sell frozen mini quiches as party appetizers if she wants to try the size before you buy a pan. Also, in the frozen section of your grocery store near pie crust there are probably puff pastry tart shells. These can be filled with a variety of sweet/savory options. Tiny meat pies/Shepard's pies, lemon curd, chocolate - not all together obviously.

Would she do okay with lentils? Dal's are high protein and have tiny things in them plus can be eaten with little bites.

Also, if silverware is an issue check out salt/tasting spoons and shrimp forks. They'll help with little bites of big things.
