If you are not overly dedicated to "chili can _only_ be made with _red_ beans" then you're looking at (in broad categories) beans and ground meat, so chili or something like it seems moderately obvious for bulk and easy to freeze. I've never made such a thing, and I consider the [recipe](https://www.certifiedangusbeef.com/recipes/Middle-Eastern-Inspired-Beef-Falafel) I found first laughable (but consider the source - they want you using beef, lots of beef) but some sort of falafel-burger hybrid would also seem reasonable, but perhaps making falafel fails your definition of "bulk" (and that recipe would not do as written anyway unless you only wanted a touch of chickpea flour to a lot of ground meat.) Meatloaf recipes with beans are common, and chickpea based vegan meatloaf recipes are common, but the intersection seems not to show up in a quick search. But viewing "all beans as more equivalent than not" I'm pretty sure you could adapt a meatloaf recipe to include both - and once you have meatloaf, sheperds (or "cottage" if you are of the "shepherds pie must be sheep based" opinion) pie is only some mashed potatoes baked on top away.
