1.Using hands, squeeze excess liquid from spinach. In a large saucepan of boiling salted water, cook pasta for 12 minutes or until tender, adding peas in last 2 minutes of cooking. Drain; return to pan.
2.Meanwhile, in a large frying pan, heat oil over moderate heat. Add salami; cook and stir for 3 minutes or until browned.
3.Add pasta mixture to salami along with spinach, garlic, parsley and onion. Gently toss for 2 minutes or until heated. Add feta; toss to combine. Season. Serve.
Omit feta and serve pasta sprinkled with grated tasty cheese instead, if liked. For a low-fat variation, use shaved ham instead of salami and low-fat fresh ricotta instead of feta. Like it spicy? Use a hot salami.
