Bumbly, would it be helpful to give you a few east to cook ideas?
I'm sure jars are fine, but I wouldn't want to eat a jar of baby food so personally never used them (other thn those Ella's kitchen pouches as out and about emergencies)
Anyway you can't do jars forever so maybe think about phasing them out a bit.
Don't feel daunted by it, try and enjoy it and have fun with it, experiment, take pics of her trying new things.
D3 is 11 months old and some easy, (and cheaper than jars), things she eats are:
pitta bread dipped in or spread with houmous, served with cucumber, a falafal, & breadsticks
little cheese sarnies, served with cucumber, tomato, dried fruit (apricots, prunes, raisins)
avocado scooped out and mashed up with a banana (she's getting a bit old for this now and doesn't like it to be mashed anymore)
fishfinger and veggies such as a corn on the cob (she knaws at it and loves these), or peas and sweetcorn, carrot batons, asparagus, tenderstem broccoli, green beans (most of that veg is really easy to pick up and eat themselves)
jacket potato with cheese and beans (she adores baked beans and makes a right mess feeding them to herself!) (I sometimes start off helping her with scooping out mash with a spoon but then I tear potato up and she picks bits up and eats them herself)
pasta with either a home made sauce I've made in the evening or at weekends that I then put into ice-cube trays and defrost them as needed.
Or pasta wit a bit of pesto stirred in
Home made pizzas. I use mini naan breads, throw on a bit of pizza topping and voila. You and DP can ave the rest of the jar of pizza topping on some grown up size naan and have home made pizzas when he gets in.
I also make things at weekends etc and freeze them for use during week,like
chicken & apple balls
spag bol
shepherds pies etc
Deserts - fruit like papaya, plums, cut in half and stone taken out, ditto nectarines.
Grapes, cut them in half lengthways if your nervous, blueberries (the most popular fruit in the world in our house and so easy for them to feed themselves and practice pincer grip with) strawberries, large one kept whole and watch them make a mess, raspberries, and the old fav - bananas.
Or a yoghurt.
Or again easy to make steam some apples, and dried apricots, or apples and berries and then freeze in ice-cubes and defrost as needed.
