Pasta is a good foundation for any easy meal, but always using the same sauces can get a little tiresome. Mix it up (literally) with a few out-of-the-ordinary things. Start by cooking your pasta. Any shape will do, though something smaller like bowties or macaroni will work best. Then you'll need cooked, peeled shrimp; cut them into bite-sized pieces if they're on the larger side. Add some chopped onion, then toss your ingredients with mayonnaise and Old Bay seasoning. If you're not familiar with Old Bay, it's a seafood seasoning with a very distinctive flavor that compliments the mild taste of the shrimp while giving it a peppy zing.
