Here's the Gurobi code to solve your optimization problem:

```python
import gurobipy as gp

# Create a new model
m = gp.Model("food_optimization")

# Create variables
oreos = m.addVar(lb=0, vtype=gp.GRB.CONTINUOUS, name="oreos")
fruit_salads = m.addVar(lb=0, vtype=gp.GRB.CONTINUOUS, name="fruit_salads")
ham_sandwiches = m.addVar(lb=0, vtype=gp.GRB.INTEGER, name="ham_sandwiches")
black_beans = m.addVar(lb=0, vtype=gp.GRB.INTEGER, name="black_beans")
hot_dogs = m.addVar(lb=0, vtype=gp.GRB.CONTINUOUS, name="hot_dogs")

# Set objective function
m.setObjective(5*oreos + 7*fruit_salads + 8*ham_sandwiches + 2*black_beans + 2*hot_dogs, gp.GRB.MINIMIZE)

# Add protein constraints
m.addConstr(17*oreos + 3*black_beans >= 72, "protein_constr1")
m.addConstr(3*black_beans + 19*hot_dogs >= 131, "protein_constr2")

m.addConstr(17*oreos + 2*fruit_salads + 25*ham_sandwiches + 3*black_beans + 19*hot_dogs >= 77, "protein_constr10")

m.addConstr(17*oreos + 3*black_beans <= 396, "protein_constr11")

m.addConstr(25*ham_sandwiches + 3*black_beans + 19*hot_dogs <= 355, "protein_constr18")


# Add healthiness constraints

m.addConstr(14*oreos + 19*fruit_salads + 11*black_beans <= 166, "health_constr11")


# Add resource constraints (already incorporated in other constraints)

# Print results
