The home side were looking to avenge Friday's 4-0 defeat at the hands of South Africa in a friendly match played at the Stade Olympique Elmenzah on Monday.
Owen Da Gama's charges found themselves on the back foot two minutes, as Tunisia took the lead through Bguir from a free-kick situation.
Dolly and Menzi Masuku had chances to level matters before the interval, but they were both unsuccessful in their attempts.
Jaziri should have made it 2-0 in the 58th minute, but the attacker failed to put the ball into the back of the net with only the goalkeeper to beat.
However, Tunisia doubled their lead seven minutes later as Amaglug-glug looked disjointed in the middle of the park.
Zaid Patel thought he had pulled one back 10 minutes from time, but the goal didn’t count as the assistant referee raised his flag for offside.
South Africa pulled one back through Dolly in the 90th minute, but it was too little too late for Da Gama’s side to launch a serious comeback.
This is how SA U23 lined-up against Tunisia U23: February, Macheke, Ledwaba, Makhele, Farmer, Nel, Dolly (c), Phiri, Mothiba, M. Masuku and Shozi.
