Myoplex and PEANUT butter. Peanut butter provides a huge punch in calories, as well as good fats and protein. Peanut butter with bread provides an amino acid balance for a complete protein (a trick vegetarians must use to get the right amout of amino acids to build muscle. With out the right amount and balance of aminos - muscle can not be built. And unfortunatly for vegetarians, animal proteins have the highest biological availability).

Peanut butter sandwiches will give you a good way to fill in caloric defecits.
