I want to learn to cook, but I have no oven or a stove. I have only a conventional oven, microwave, and propane grill. What are some things I can still make?

if you have a grill u can make all sorts of things, it depend son what u like

Take steak. Salt and pepper. Place on grill. Wait. Flip. Wait. Eat.

And Mushroom

Grill is your best option, I like to go with shiska-bobs with chicken, green peppers, onions, pineapple, tomato

you cna saute using your grill and do anything on your grill your options are endless

you could make a lot of hot dishes with oven
otherwise can't think of too much
although i guess you could buy a crockpot too

think of easy recipes, ie pasta, or any plain based meats ( steak, pork chops, burgers etc. )

over-starting your pursuit will only leave you with great grief

whats the difference between oven and conventional oven? is the latter fire-powered instead of electric?
