I'm having trouble with ModuleScript communications?

In my game, I have a part that represents a spawning zone for food, in that part, there is a normal server script that fires a function within a module script to spawn food, once that food is eaten, the food then disappears, but how do I tell the server script that initially fired the spawning function within the module script that the food has been eaten so the server script can spawn another food.

So far, I am currently using a ChildRemoved event but I have a feeling this method is poorly optimised, how would I go around this?

Server Script

spawnPart = script.Parent
Food = game.ReplicatedStorage.Assets.Nut
waitIntervals = 50
for i = 1, maxFood do
    petModule.GiveFood(Food, spawnPart, waitIntervals) -- petModule is the module that spawns the food using Clone()
end

Module Script

module.GiveFood = function(FoodModel, spawnPart, waitIntervals)
    coroutine.resume(coroutine.create(function()
        local Food = FoodModel:Clone()
        foodTable[Food] = {}
        foodTable[Food]["Food"] = Food
        foodTable[Food]["currentPlr"] = nil
        foodTable[Food]["deSpawn"] = false
        foodTable[Food]["Food"].Parent = spawnPart
        local baseHealth = foodData[foodTable[Food]["Food"].Name]["Health"]
        local xPos = math.random(-spawnPart.Size.X/2, spawnPart.Size.X/2)
        local zPos = math.random(-spawnPart.Size.Z/2, spawnPart.Size.Z/2)
        local yPos = Food.Size.Y/2 - 0.1

        foodTable[Food]["Food"].CFrame = spawnPart.CFrame * CFrame.new(xPos,yPos, zPos) * CFrame.Angles(0,math.random(1,36)*10,0)
        foodTable[Food]["Health"] = baseHealth

        foodTable[Food]["Food"].ClickDetector.MouseClick:Connect(function(Plr)
            if foodTable[Food]["currentPlr"] == nil then
                if Pets[Plr]["Robot"] then
                    if Pets[Plr]["Feeding"] == nil then
                        gatheringFood(Plr, foodTable[Food])
                    elseif Pets[Plr]["Feeding"] ~= nil then
                        local preFood = Pets[Plr]["Feeding"] 
                        foodTable[preFood]["currentPlr"] = nil
                        foodTable[preFood]["Food"].FoodHealth.Enabled = false 
                        gatheringFood(Plr, foodTable[Food])
                    end
                end
            --------------------------------
            else
                if Plr == foodTable[Food]["currentPlr"] then
                    foodTable[Food]["Health"] = baseHealth
                    foodTable[Food]["Food"].FoodHealth.Enabled = false 
                    foodTable[Food]["currentPlr"] = nil
                    PetGatherStop(Plr)
                end
            end
        end)
        wait(math.random(waitIntervals,waitIntervals + waitIntervals/2))
        if foodTable[Food] then
            foodTable[Food]["deSpawn"] = true
            if foodTable[Food]["currentPlr"] == nil then
                foodTable[Food]["Food"]:Destroy()
                foodTable[Food] = nil
            end
        end
    end))
