Create a many-to-many link table:

combo_id    meal_id
1           1
1           4
1           7
1           9
2           2
2           5
2           8
3           3
3           5
3           6
3           9

To select all meals for a given combo:

SELECT  m.*
FROM    combo_meal cm
JOIN    meal m
ON      m.id = cm.meal_id
WHERE   cm.combo_id = 1
