Let's solve the expression step by step, following the order of operations (PEMDAS: Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

Given expression:

\[
17 + 2 \times 15 + 7 - 23
\]

1. First, handle the multiplication:
\[
2 \times 15 = 30
\]
Now the expression becomes:
\[
17 + 30 + 7 - 23
\]

2. Next, perform the addition and subtraction from left to right:
\[
17 + 30 = 47
\]
\[
47 + 7 = 54
\]
\[
54 - 23 = 31
\]

Thus, the value of the expression is:

\[
\boxed{31}
\]
