Whisk up an egg or two, add cubes of cheese/cold meat/bits of cooked veg, a bit of cream or full fat milk and a few tablespoons of flour. Fry spoonfuls as fritters or bake in greased muffin tins - this basically contains all the food groups and is really delicious. And it's solid so not too much mess. Yes, it's a bit greasy if fried but babies need a lot of fat. You can also bake the mix without the flour in muffin tins lined with pastry (can buy this if not confident to make it yourself).
Pasta and pesto (pesto is insanely easy to make if you have a blender so it needn't be v salty) is good and not too messy.
A fork is good starter cutlery for cubes of fruit or cheese or whatever - DD used to love stabbing them.
Toasted sandwiches which can contain whatever you like. I used to do broccoli/cauli and cheese toasted sandwiches. You don't need a toaster - you can just put whatever in the bread and butter outside of sandwich lightly and fry in a frying pan on a low heat.
Risotto is pretty easy to pick up for a baby if quite dry.
Quick cook polenta - stir in nuggets of chopped frozen spinach or frozen peas/sweetcorn or leftover cooked veg, grated cheese and tomato puree (and bits of cold meat if you want). Allow to set in a tin and cut into slices and fry for a crispy outside (or it is perfectly OK just set and sliced cold).
Pizza topped with anything you want her to try the taste of and whatever the topping is can be cut up small.
Roll out pastry v thin and add veg/meat/whatever cut up small then make little pasties. I used to do fried mince of various kinds and add veg and sometimes even a bit of cream or cheese.
Something called cook up rice which is a West Indian dish - you fry onions and any other veg you like cut up small, add a tin of beans without liquid of whatever kind (we like blackeye beans but kidney beans or haricots or anything work well, and we add a chopped red or green pepper as veg). Add creamed coconut which is available in blocks (about a third of a block to a small cup of rice). Measure the rice by volume and add twice as much water and/or the liquid from the tin of beans. Cook in a covered pan that water can't escape from in a v low oven or over a VERY low heat for twenty minutes or half an hour - sticky and easy to pick up for a baby. You could add meat or fish but there is plenty of protein with the beans. You can also add spices or herbs at the frying stage if wanted - smoked paprika or ordinary paprika isn't spicy and works well, also thyme, cumin, ground coriander etc.
Hope some of this is helpful!
