Wow some people are being a bit mean here. The OP is asking for help not a telling off.
My baby is just a couple of weeks older than yours, OP and we are getting into the swing of food a little bit now, after a bumpy start 
I was very daunted by it all, but have found it gets easier.
We have a very small galley narrow kitchen (nowhere for a family table etc) so what I do is carry the highchair to the kitchen door and sit the baby there (away from the oven and hobs) so I have time to make his food without him being upset he can't see me!
I give him something to nibble at as I cook (usually a piece of mild cheddar, a finger of toast, a strawberry or lump of banana). Sometimes he eats this, sometimes he mushes it into his hair or drops it over the side, but it keeps him entertained.
If I need to do something very quick and I have nothing in I will scramble one egg in a small frying pan with a bit of butter.
Otherwise what I do is keep something back from our evening meal and fiddle around with it for the baby the next day. I tend it make it into two portions, and give him half for lunch and half for dinner that evening.
So today he has had cauliflower and broccoli cheese for lunch because we had cauliflower and broccoli as vegetables last night with our sausages and mash. I took out a few bits of potato, brocc and cauli as I was serving up last night and put them in the fridge. Today I took them out, mashed them up a bit so they were soft enough to eat, sprinkled some cheddar on and popped it in the oven to warm it through and melt the cheese.
Yesterday he had pork with rice and broccoli, again I'd fished out bits from our food last night before adding our sauce/salt to it. I mashed this all up with a bit of water using my soup blending stick as I don't have a food processor, it worked fine.
Tonight for tea we are having pasta with chilli and chorizo, so I'll put some plain pasta aside for the baby before adding the sauce, and tomorrow I'll reheat it, with some frozen peas and a bit of trout ( I bought one fillet and cut it into six bits and put it in the freezer to use for the baby).
Hope this helps
