Sounds like you've got the makings of a decent braise! Brown the meat, take it out and add the veggies, then deglaze with the tomatoes plus stock/wine/beer/water/whatever's on hand. Add the meat back in and cook it all low n' slow until the meat's falling off the bone. Cook the rice separately and serve on the side. Braises always taste better after a night or two in the fridge so they're great to make ahead.

To me, one pot meals are fall/winter foods, but they are delicious all seasons. Chicken and rice or chicken cacciatore? Cooks Illustrated has a good chicken and rice. I'm sure Google could find it for you.

something in the tone of your question suggests tired, woebegone, not much interest in cooking. and yet you need to eat? what pops into mind? the "sludge" recipe from MFK Fisher. A joy to read, if you don't know it. Easy to cook and eat. here's one version, or go to the books...http://www.fourpoundsflour...

Probably too late now, but Food52 had a One Pot Dish Contest so that may be helpful next time. But here are the results from a search results of "one pot" in the article drop down: https://food52.com/blog...
