## Step 3: Implement the optimization problem using Gurobi
```python
import gurobi as gp

# Define the model
m = gp.Model("optimization_problem")

# Define the variables
x0 = m.addVar(name="bagged_salads", lb=0)
x1 = m.addVar(name="oreos", lb=0)
x2 = m.addVar(name="tomatoes", lb=0)
x3 = m.addVar(name="bowls_of_cereal", lb=0)
x4 = m.addVar(name="green_beans", lb=0)

# Define the objective function
m.setObjective(6.92 * x0 + 1.13 * x1 + 9.28 * x2 + 8.53 * x3 + 3.56 * x4, gp.GRB.MAXIMIZE)

# Add constraints
# Protein constraints
m.addConstr(4 * x0 + 2 * x1 + 5 * x2 + x3 + 4 * x4 <= 63)
m.addConstr(x3 + 4 * x4 >= 4)
m.addConstr(2 * x1 + x3 >= 9)
m.addConstr(4 * x0 + x3 >= 8)
m.addConstr(4 * x0 + 2 * x1 >= 6)

# Iron constraints
m.addConstr(3 * x0 + x1 + 4 * x2 + 2 * x3 + 4 * x4 <= 115)
m.addConstr(3 * x0 + 4 * x4 >= 15)
m.addConstr(x1 + 4 * x4 >= 16)
m.addConstr(3 * x0 + 2 * x3 + 4 * x4 >= 23)

# ... add all other constraints ...

# Solve the model
m.optimize()

# Print the solution
if m.status == gp.GRB.OPTIMAL:
    print("Objective: ", m.objVal)
    print("bagged_salads: ", x0.varValue)
    print("oreos: ", x1.varValue)
    print("tomatoes: ", x2.varValue)
    print("bowls_of_cereal: ", x3.varValue)
    print("green_beans: ", x4.varValue)
else:
    print("No optimal solution found")
