Lior bagels (plural) are two items. You dont need to berachos or even two minim (though lol DY) You need to manos = portions. Assuming a bagel is a portion, two bagels is a perfectly valid shaloch manos. See Mechaber 695:4 where he identifies “shtei manos basar” as a kosher Shalach manos.
That being said, as discussed in the kezayis thread, generally we dont try to fulfil mitzvos to the bare minimum, as the mechaber explictly says in this case “vechal hamrbeh lishloach lerei’eim harei ze meshubach”
