My ds has just turned one and he has quite a good varied diet.
He usually has weetabix with fruit for breakfast with yoghurt.
Lunch I try and give him something he can eat himself - sandwiches, toats, bacon cut into chunks, mini babybel, mini pizza, potato wedges etc etc
Dinner he usally has what we eat - curry, chilli, spag bol, macaroni cheese, roast, scrambled egg, sausage and mash, nuggets.
At this age they can eat almost anything - I usually make spag bol from scratch but we make lasagna using jar sauces and we give him that. i think they are ok in moderation, so long as your not always using them because of the salt content.
To make spag bol -
brown some mince, onion and garlic
add carrots, celery, red pepper, mushrooms, 2 cans of tin tomato's a couple of stock cubes and some tomato puree and then leave it to simmer for about 15 / 20 mins
Have you tried looking at the Annabel Karmel book - it's got loads of easy recepies in it - ones you can make for the whole family.
