I too enjoy cooking aboard and have often entertained.
1. Coffee. Aeropress. It's a mini 1-cup French Press. Works better than a French Press and is easier to clean-up and store. Would NOT work for a crowd, but would work for times when a single guest will have coffee.
2. Range. A good friend just installed a 3-burner Dometic RV stove on his Roughwater 37. He likes it a lot. Less than $400 vs $1000+ for Force 10. I noticed trend with sailboat cruisers is lots of solar and induction cooktops which work well and are fantastically energy efficient.
3. Instant Pot. I used to have a slow-cooker and a pressure cooker aboard. No more - ditched those and now have a small size Instant Pot.
4. Tin Foil Trays from Costco. When I did entertain, I would buy the tin foil lasagna trays from Costco. They fit perfectly in a small oven or the Breville SmartOven (large toaster oven). Instead of lasagna, try baked ziti (no need to pre-cook pasta). Other dishes include shepherds pie, baked beans, chicken cacciatore, and others. Pick-up a copy of "Dump Dinners" for your Kindle. Some recipes are junk, but there are a few nuggets of no-prep meals that are pretty good.
5. The Blackstone. For Weebles 2.0 (refit), I am not going to have a BBQ grill. I am replacing with a Blackstone 22-inch griddle. You can cook anything except chicken soup on this thing, and it's easier to clean, and incredibly easy on propane. And it keeps smells and grease out of the galley.
