The stored procedure returns the result set you want - why complicate it (and double the execution time)?

You may have simplified things a little to help - in which case, you could run the results of the stored procedure into a #temp table and join to it in your query:

CREATE TABLE #Projects (project_name VARCHAR(stringsize))

INSERT INTO #Projects (project_name)

EXEC STORED_PROC_NAME '%20%Catalog%'

SELECT g.project_name

FROM Groups g

INNER JOIN #Projects p

ON p.project_name = g.project_name
