Budget childhood meal. Parsley from the garden, clams from a can. All out of linguine but sauce holding Fusilli was available.
Cost per person: $3.33 It, um,used to be cheaper. But canned protein costs have grown faster than inflation over the last 4 decades.
Save the clam juice and use the technique where you finish cooking the pasta in the pan with a little pasta water, but also add in the clam juice.
