Weaning is definitely a time to reassess your own eating habits.
neither of us have the time to spend cooking up food for her, freezing it and then preparing it for her after a full days shift
Who has time to cook a separate meal for baby?! And honestly @CJ98 - you don't have time to defrost and reheat a pre cooked meal but you do have time to order and await a takeaway? Do you literally subsist off takeaways/pizza every night?
Have you got a slow cooker? Air fryer? Microwave? Toaster?
You can microwave a packet of rice in 1m30secs and it doesn't take much longer to steam a piece of fish and some packet/frozen veg also in the microwave.
You can empty a packet of chicken thighs into a slow cooker with a tiny splash of water leave it on all day and pull it when you get in, mix it with a bit of BBQ sauce (low salt, not even homemade will do, but no honey under age 1) or soy or whatever flavour you fancy (lemon and black pepper), serve with wraps and cucumber or a few slices of avocado and quarters of tomato, grated cheese.
You can slice some potatoes into wedges and bake with courgette, lemon and a salmon fillet them in less time than it takes for a takeaway to arrive.
You can cut a thick slice of sweet potato and toast it in your toaster. Stick some cottage cheese on top, slices of pepper and a handful of blueberries on the side, whatever!
Stick a slice of toast on, and while it toasts mash a banana then spread it on toast. Sprinkle of cinnamon or cocoa powder if you must. You could even mix cocoa powder into the mashed banana, a All in the time in takes to toast some bread.
Keep it simple. It doesn't have to be a multi course gourmet meal. Whatever you manage to cook/prepare, siphon off a taster for baby to try the next day, no need to freeze.
What she doesn't need at 7m old is added sugar, chocolate buttons, snacks. She has so much time to discover those much later down the line.
ETA - ok, scrap the fish and banana suggestions, just seen you're allergic so can't prepare those. But there are so many things are doable quickly that you can adapt to your allergies.
