Shrimp and Mushroom Linguini

So I kind of made this up and Lyle and Mika said they loved it so you guys can try it out too if you want. I was trying to find a good shrimp pasta recipe (because I was craving it) and saw a lot of good stuff in many different recipes and kind of put what I liked and took out what I didn't :)

1/2 pound of shrimp
1 package of linguini
1 package mushrooms
1/2 a large onion
3 cloves of garlic
4 tablespoons of butter
4 tablespoons of olive oil
salt and pepper
lemon juice (about a tablespoon?)

So you cook the pasta first. While that is cooking you saute the onions and garlic in half of the butter and olive oil. Saute until onions are translucent. While you do that salt and pepper the shrimp. Then you add the mushrooms and shrimp and saute for about 1 minute. Add lemon juice and salt and peper. Drain pasta and add the rest of the butter and olive oil. Then add the sauce to it. It should feed about six people. In our house it served me, mika and lyle. (lyle had thirds ;)
