I've not tried any of Linda McCartney's stuff- to be honest, veggie sausages always look a complete let down,
I can tell you Linda' veggie sausages are singularly toothsome. Love 'em. Go well chopped in a hearty veggie casserole for instance.
To the OP - don't forget you can do just about anything with pasta. For instance. chop up an aubergine, drizzle it with oil and roast it in the oven. Then throw it in with pasta, tomatoes maybe olives or capers and loads of herbs, pepper. Grate some veggie parmesan on the top.
