Cook pasta al dente. Slice the vegetables lengthways (best with a peeler), then cut into thin strips. Pluck the sage. Melt fat. Swirl the sage in it. Steam the vegetables for 2-3 minutes and season a little. Fold in the pasta, heat briefly. Season the creme fraiche with salt, pepper and paprika and serve with it.
Also tastes good without creme fraiche, but very good with a bowl of salad.
