Numbers 11:5

אשר נאכל במצרים חנם [WE REMEMBER THE FISH] WHICH WE DID EAT IN EGYPT FOR NOTHING — If you say that they meant that the Egyptians gave them fish for nothing (without payment), then I ask, “But does it not state, (Exodus 5:18): [Go, therefore, now, and work], for there shall no straw be given you”? Now, if they did not give them straw for nothing, would they have given them fish for nothing! — What then is the force of the word חנם? It means: free from (i.e. without us having been burdened with) heavenly commands (Sifrei Bamidbar 87). את הקשאים THE CUCUMBERS — R. Simeon said, “Why did the manna change its flavor into that of anything one wished (as the Midrash states) except into these vegetables here mentioned, the taste of which it appears not to have assumed since the people lusted for them? Because they are injurious to nursing mothers. So indeed people say to a woman: Do not eat garlic and onions on account of the baby. A parable! This may be compared to a king, etc. as it is related in the Sifrei Bamidbar 87. הקשאים These are concombres in O. F., (English = cucumbers). אבטיחים are boudekes in O. F. (English = melons). החציר are leeks, porels in O. F. [The Targum renders the names of the vegetables by בוציניא etc.].

זָכַ֙רְנוּ֙ אֶת־הַדָּגָ֔ה אֲשֶׁר־נֹאכַ֥ל בְּמִצְרַ֖יִם חִנָּ֑ם אֵ֣ת הַקִּשֻּׁאִ֗ים וְאֵת֙ הָֽאֲבַטִּחִ֔ים וְאֶת־הֶחָצִ֥יר וְאֶת־הַבְּצָלִ֖ים וְאֶת־הַשּׁוּמִֽים׃

We remember the fish, which we did eat in Miżrayim for nothing; the cucumbers, and the melons, and the leeks, and the onions, and the garlic:
