I always carry a full size convection oven, in case I want to cook a turkey.

Seriously though, get a isobutane backpacking stove for $7 like this one that's less than 4 oz: https://www.amazon.com/Backpacking-Lightweight-backpacking-ultralight-Windproof/dp/B0BJ2DXTFV/ref=asc_df_B0BJ2DXTFV/?tag=hyprod-20&linkCode=df0&hvadid=632029843327&hvpos=&hvnetw=g&hvrand=16439769936117930868&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9010447&hvtargid=pla-1946488665268&psc=1

AND fuel at any walmart/sports store for less than $7: https://www.walmart.com/ip/Coleman-Butane-Propane-Mix-Fuel-7-75oz/20595064?wmlspartner=wlpa&selectedSellerId=0&wl13=1339&adid=2222222227720595064_117755028669_12420145346&wmlspartner=wmtlabs&wl0=&wl1=g&wl2=c&wl3=501107745824&wl4=aud-1651068664946:pla-294505072980&wl5=9010447&wl6=&wl7=&wl8=&wl9=pla&wl10=8175035&wl11=local&wl12=20595064&wl13=1339&veh=sem_LIA&gclid=CjwKCAiAxvGfBhB-EiwAMPakqor7f8svkz91AfN474tHgZQZLuNkomxsDfV6If2KBoKNWsKg5L6HpxoCplEQAvD_BwE&gclsrc=aw.ds

With a hot plate you have to find an electrical outlet, with a stove you can go anywhere.

If you want to spend more get a Jetboil - it's more efficient, uses less gas, cooks faster.

An alcohol stove would be another option: https://www.amazon.com/Esbit-Lightweight-Trekking-Anodized-Aluminum/dp/B001UEL76Q/ref=asc_df_B001UEL76Q/?tag=hyprod-20&linkCode=df0&hvadid=167119746601&hvpos=&hvnetw=g&hvrand=1057770790670964651&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9010447&hvtargid=pla-84153121286&th=1
