Please help with ds2 eating

[tinypop4]

Getting to thin end of the wedge with ds who is almost 2 years old.
He eats breakfast, he eats a picky or sandwich type lunch. Every single night without fail dinner is a huge drama unless it is sausages and pasta which the rest of the family don't want to eat every day.
I cook simple meals that he has eaten in the past, usually rice or pasta based or a mild fish or chicken pie. I don't let him snack in the afternoon so he is definitely hungry as he gets grizzly and starts opening the fridge.
He screams and shouts for 5 minutes. I get him down. He gets back up and screams again while pushing the food away. I get him down, he screams for bananas and blueberries which I don't serve as I don't think it's a balanced meal.
After about 30 mins of wandering around whining he will sometimes get up and eat a bit or will carry on till bedtime routine starts.
I don't show frustration or anger but o sure as he'll feel it and don't know what to do for the best. Meal times are becoming unpleasant and he is not getting a decent range of nutrients Over the course of the day. He's never drunk milk so I can't make up calories or nutrients with it.

Sounds tricky. Suggestions that I have - give me a small snack before dinner so he is not over hungry. Or give one thing you know he likes on the plate with the other food to start him off. E.g. A few blueberries as if they are part of the meal. Offer more variety that just pasta/sausages but make sure all the dishes reappear regularly. E.g. Three options twice a week. Fourth on Sunday. Try to distract him at the meal table.

Finally maybe if all else fails just give him what he does want, but gradually introduce a new food. E.g. Peas one week added to plate, carrots next, chicken next. In small quantities. This may seem like giving in but you don't want to end up in a power battle over food. A more soft approach may be more effective. In a few weeks he may have a new favourite or have forgotten to be fussy. Whereas if you force the issue he won't forget iyswim.

Thank you fanny I appreciate your response. I've started to get anxious at mealtimes because I know he is going to kick off whatever it is! I think I do a good job of pretend calm but it's so annoying and stressful! He's a skinny bones anyway I need him to eat!!
I will try your suggestions

Also I would keep putting milk out every so often. My dd didn't like it but ds love it so it was always around and now she loves it too.

I agree with offering one thing that he does like...if for eg. dinner is potatoes and fish, cook just a small amount of pasta and have that available.

That's what I did with awkward DD2...she's 9 now and always eats her meals.
