Canned beans are fine. No need to gum up a pressure cooker in an attempt to save time and rush through the cooking part. Just open a goddam can of beans.
Red Kidney beans are still kidney beans and are not traditionally used in beans and rice.
They work fine for chili and a few other recipes but fail to provide the creaminess of red beans or pintos. Red beans are available online and at some(better) grocery stores.
No matter what you're cooking substituting the wrong ingredients will never yield the best results. Rushing through a recipe, failing to plan ahead, and taking shortcuts will also lead to less than optimal results.
