Mushroom risotto, using dehydrated mushrooms, an onion, Arborio rice, and some veggie (or chicken) stock (include the mushroom rehydrating water in the stock) is another good one. If you have some parmesan to add, that gives nice depth.
I have done a large batch of onion and garlic "base" in the past when I have had a glut, and frozen it in 1 cup batches. That makes very easy starts to tomato sauces for pasta or curry sauces for rice and defrosts fine.
So a bag of pre-made onion and garlic, a tin of tomatoes, some peppers in oil and some bacon lardons (long life) are easy from the storecupboard.
Or a bag of onion/garlic with a spoon of ginger paste (very long life jar stored in the fridge), a couple of tablespoons of curry powder or curry paste, add a tin of coconut milk, a squirt (highly technical quantity!) of tomato puree from a tube, and whatever meat/veg you have from freezer/tins, along with some extra vegetable/chicken/fish stock if you need to dilute it a bit.
Another storecupboard essential for me is bags of ready-diced meditteranean veggies in the freezer. Either when I get a glut that needs to be used, or I know I have a busy time coming up, or I am doing a large batch for an event and leftovers is ok - I do this - and freeze the results before cooking to throw into the oven/on the BBQ in foil packets, or freeze cooked leftovers to toss into tomato sauces or just reheat as a side dish. Quantities are approximate, the mix is what you have and what your family likes. The most important thing is to try and get the SIZE of the dice about the same on all veggies in the batch so they cook in about the same time - sometimes they're large (maybe 3-4cm dice) for BBQ purposes, other times only small (maybe only 1cm) for roasting and sauces.
A couple of red onions (yellow are fine, red looks and tastes slightly nicer), maybe 3-6 whole cloves of garlic (the only thing not diced, unless they are massive), red and yellow peppers, mushrooms, courgettes, cherry tomatoes (regular tomatoes are fine), aubergine (if your family like it - mine don't), French beans work well, etc.
Toss them in a large Ziploc freezer bag. Pour in a glug of olive oil, a smaller glug of balsamic vinegar, season well with salt, pepper and some dried herbs (oregano, basil, thyme and rosemary are all good - and mixed is perfect). Shake to mix, and allow to marinate for at least 20 minutes - they can be made 1 day ahead of using, frozen before cooking, or only made up just 20-30 minutes before you cook.
Roast at 180 degrees until cooked - about 20-25 minutes for 1cm dice, longer for larger pieces.
If I am making a batch specifically for the freezer, I will try to open freeze them so they will pour out of the bag easier and I can take out just what I want from a large batch.
Tinned clams are good in pasta or Chinese style sauces, or to make a seafood risotto.
