What can I say, カボチャ is a very prominent plant here, and the only substitute I have for squash.
Half a japanese pumpkin, sliced thin
Green and red peppers
Short, twisty pasta or bowtie pasta
Cook the vegies on med-low heat, using oil.
Boil the pasta. I found a brand that cooks in two minutes.
Drain the pasta, stir it into the veggies with oil and spices
sprinkle in lemon juice
Enjoy. I find the sweetness of the pumpkin compliments the lemon.
