A quality immersion/stick blender can do 95% of what a traditional blender can and quite a bit that a blender just can't. I even make hummus with mine (this takes a while longer than a food processor, but I'm usually fairly pleased with the results) and cleanup is quicker.
I think corelle dishes are ugly, but I've dropped mine multiple times on my tile floors and they're oven safe, which comes in super handy.
I love silicone bakeware. You can smoosh it to fit in small cabinets and you never have to take up valuable sink/counter space to soak it because baked on food just wipes away.
Board scraper/bench knife/dough cutter is my favorite multitasker. General purpose scraping/pounding tool, blunt force churchkey, meat tenderizer/hammer (using the handle - in a pinch, or with lots of practice), ice pick, pulled meat shredder, I made mashed potatoes with one once. My real point here is to find new uses for the few tools you already have.
Do everything you can to minimize cleanup and amount of dishes that you use.
