Your biggest impedance is your insistence on eating the food you're trying to photograph.
Prep the food for photography and not eating if you want the photos.
Can't over-stress the importance of this (and I think it might have already been mentioned once or twice).
But there is nothing that I am willing to do about it.
I was a wartime baby and food was rationed so I am not willing to paint etc good food and then throw it away.
I am self publishing and will do the best that I can with real food.
Jamie Oliver and Loftus use real food ;-)

I highly value these words. Don´t waste food for whatever purpose. Food is thrown away every day without people thinking what effect that has on your food prices and of the prices of food for the poorer regions in the world. The more you throw away, the more expensive food will get, believe it or not. And it does make a huge difference for poor people if rice costs twice as much or even more.
Beside that real food has been a trend for the last few years. Many people and media (but not all) prefer that to the rather unreal look of the years before, using glycerine, etc.. You can use oil though to keep the food "alive" a little longer.
In regard to your photography:
In your first image you used a 35mm f1.8 lens, but you closed the aperture pretty much to f5.6. Modern food photography works with rather shallow depth, so experience with smaller numbers and you´ll see a big change. Also try to use longer lenses to get an even shallower focus and more blur.
Get lower with your camera and shoot more horizontal to get even more blur to the background
The light streaks from the table are from the back, but the reflection comes from the right IMO. However, I wouldn´t mind the reflection too much - if you used a white plate instead, that wouldn´ be a problem at all.
You could use the window as a second light source though - open it!!! I´d use it as the main light and use the flash as backlight, BECAUSE: backlight is your biggest friend when it comes to food photography. I wouldn´ worry too much about color temperature of the different lights. Both should be close to daylight when you cook your lunch

, and the table probably changes the light color more than a cloud outside would.
I´m not the biggest food photographer, but here is just one of my straight out of camera shots to show you what pretty simple backlight can do.

I could have cleaned the silverware though
To be honest I don´t like the table too much. Think about getting some old wood - be it real wood, or parquet floor that you can quickly set up and tear down (not the kitchen material I have used - that looks too artificial).
