21 month old here. Breakfast is a choice (usually dictated by me 
) of: porridge or weetabix with or without raisins, or fruit (banana/pear/grapes if they’ve all I’ve got in but try to avoid as very sugary), or yogurt. Doesn’t normally want yoghurt.
Lunch is only usually together on weekends because he’s in childcare during the week. Weekends will be eg brunch food (eggs, tomatoes, hash brown is offered but he doesn’t like it, toast, ham or smoked salmon which he adores), or sometimes we go out. Recently we went to a Japanese restaurant so he had a chicken skewer and some prawns, tried but rejected edamame beans, and merely observed the sushi. Enjoyed ice cream for dessert. We also enjoy sharing a baked Camembert at the local pub, he dips the bread himself and always eventually overdoes it on the accompanying chilli jam and complains about his poor tongue 
Dinner is usually either a pasta dish (tomato based usually, with chicken or sausage or a beef stew) or rice with an accompanying meat (chicken Kiev, breaded fish, chicken breast, a casserole or stew with lots of veggies). Often a side salad- lettuce which he recently started eating, sweetcorn (very popular!), tomatoes, and cucumber which he can take or leave. Peas have been a big hit lately.
Snacks include mini cheddars, very occasionally popcorn but not for a while now, fruit, toast with peanut butter (yum) or jam (he’s not so keen). Hope that’s all suitably inspiring...!
