Your little one is the same age as my DS and so far (I am well aware that this could change as they all see to go through a fussy stage) he will eat anything but in front of him. He does of course have his favourites but he will try anything.
We are lucky because both me and DH love cooking, it's one of our joint hobbies. So for us, baby led weaning was quite easy and a natural transition. I would echo some of the ideas above about trying to get your OH to eat healthier, homemade versions of his favourite treats. We often eat pizza, burgers etc but we make it all from scratch do we can control the salt content and flavours which is good for baby but also means we can still have our favourite treats. If your OH is really opposed to veg, it's still important to include them on your DD's plate so get stocked up on frozen veg and tins of sweetcorn etc so that you can quickly add something to your plate. My DS absolutely loves green beans and broccoli! I also stock up on fruit from Asda so he has raspberries/strawberries/blueberries/banana/pineapple every day. This is something you can give as a desert either with or without greek yoghurt that your partner doesn't have to eat.
I would highly recommend the books by Rebecca Wilson (What Mummy Makes and Family Comforts) as these have a mixture of quick and longer recipes that range from curry to eggy bread to meatballs and garlic bread. They gave me the confidence to go on and adapt all the recipes I've made over the years and make them suitable for DS. Indeed, tomorrow we are using our tried and tested recipe for butter chicken curry with homemade naan that we have tweaked slightly in terms of chilli/salt content and is one of DS' favourite meals.
I was really nervous about food for him at first but as he is (currently) not a fussy eater and will eat my homemade food, I feel more confident giving him treats every now and then...today we had relatives round so I made triple chocolate brownies and felt confident in his food intake over the past few days to let him have a small piece - he loved it!
If you struggle to find the time to cook from scratch every day, batch cooking is your friend...there are loads of ideas online for BLW batch cooking.
What I will say is don't give up! Firstly, don't be disheartened if food prep takes a while...I remember when me and DH first started cooking years ago, I think it took me about 15 mins to chop one onion!!! You do get quicker, more confident and ultimately better! Secondly, persevere with the food choices for DD...she may refuse them at first but it can take several times for a food to be introduced before they will eat it!
I hope that long essay (sorry!) was useful! Good luck!
