## Step 1: Define the symbolic representation of the problem
The symbolic representation of the problem consists of pairs of variables in symbolic notation and their corresponding natural language objects, the objective function rendered as an algebraic term, and the list of semi-algebraic constraints.

## Step 2: List the variables and their corresponding symbolic notation
The variables and their corresponding symbolic notation are:
- cheeseburgers: x1
- steaks: x2
- potatoes: x3
- apple pies: x4
- apples: x5
- hot dogs: x6
- kale salads: x7

## Step 3: Render the objective function as an algebraic term
The objective function is:
4 * x1^2 + 4 * x1 * x3 + 5 * x3 * x4 + 6 * x3 * x5 + 2 * x3 * x7 + 7 * x4^2 + 4 * x4 * x5 + 2 * x5^2 + 8 * x5

## 4: List the semi-algebraic constraints
The constraints are:
- 20 * x1 + 5 * x2 + 19 * x3 + 23 * x4 + 12 * x5 + 25 * x6 + 21 * x7 >= 34
- 20 * x1 + 26 * x2 + 19 * x3 + 23 * x4 + 12 * x5 + 25 * x6 + 21 * x7 >= 26
- x1 * x4 + x5 * x5 >= 49
- 5 * x2 + 21 * x7 >= 33
- x4 * x4 + x6 * x6 >= 39
- x1 * x1 + x6 * x6 >= 45
- 5 * x2 + 19 * x3 >= 24
- x5 * x5 + x7 * x7 >= 16
- 19 * x3 + 21 * x7 >= 43
- 5 * x2 + 25 * x6 >= 17
- x1 + x4 >= 36
- x1 + x2 + x6 >= 36
- x3 + x4 + x6 >= 36
- x4 + x5 + x6 >= 36
- x1 + x5 + x7 >= 36
- x1 * x1 + x2 * x2 + x6 * x6 >= 36
- x3 + x4 + x6 >= 36
- x5 * x5 + x6 * x6 + x7 * x7 >= 36
- 4 * x1 + 28 * x2 + 3 * x3 + 13 * x4 + 8 * x5 + 4 * x6 + 7 * x7 >= 41
- ... (rest of the constraints)

## Step 5: Output the symbolic representation of the problem

# ... (rest of the constraints)

# Optimize the model

# Print the solution
