Use EXECUTE sp_executesql @sql, here is example:

create proc sp_DynamicExcuteStore 
@TableName varchar(50),
@ColumnNames varchar(50),
@SQLResult varchar(max)
as
declare @sql nvarchar(max) = '
INSERT INTO '+@TableName+' ('+@ColumnNames+')
    EXEC sp_executesql '+@SQLResult
EXECUTE sp_executesql @sql
go
create proc sp_test
as
select 'test' + convert(varchar,RAND())
go
CREATE TABLE [dbo].[Test](
    [text1] [nvarchar](500) NULL
) ON [PRIMARY]

GO
DECLARE @return_value int

EXEC    @return_value = [dbo].[sp_DynamicExcuteStore]
        @TableName = N'Test',
        @ColumnNames = N'text1',
        @SQLResult = N'proc_test'

SELECT  'Return Value' = @return_value

GO

SELECT TOP 1000 [text1]
  FROM [test].[dbo].[Test]
