I buy a huge bag of peeled whole garlic cloves from an Indian shop and freeze them, then use as needed. One of those big stainless steel garlic mashers with a handle that you rock back and forth crushes it without having a jammed garlic crusher, very easy to clean. Frozen casserole and stew mixes in addition to mash, pastry, soffrito. Easy mash, wash and cook spuds whole in a microwave rice cooker, peel when cooked but still hot to warm using a paring knife, skin comes off easily. Microwave again in milk, cream, butter, evoo or ingredients of choice. Mash with hand masher or blender stick. Frozen onions make a nice addition added before the milk/cream/butter. I only buy frozen broccoli now, found fresh went brown to quickly but on the odd occasion my partner buys it, I wash, slice the whole head down the middle through head and stem then cook whole, head down, then chop and trim afterwards. Ditto cauliflower. Swede, wash and microwave in a shallow dish of water until softer, much easier to cut and pare off the skin. I do the same with smaller pumpkins if I'm using the whole thing.
